Opis:
The light-emitting diode (LED) is an essential component of intelligent street lighting (ISL) systems. An efficient ISL system can not only reduce power consumption by planning LED illuminating time but also reduce maintenance costs through a high degree of automation. In this paper, a buck-boost converter is used to realise composite transmission of power and signals for an ISL system. The power is modulated by the pulse width modulation (PWM) approach, and the switching ripple generated in the PWM process is utilised as the carrier of the signals transmitted between the remote-control centre and the slave nodes. Moreover, the proposed model involves a ‘request to send (RTS)/confirm to send (CTS)’ mechanism to avoid signal conflicts. Compared with the conventional power line communication (PLC) approach, the proposed transmission scheme has the advantages of simple circuit structure and simple system wiring. Additionally, a simulation model built in MATLAB/Simulink proves the designed transmission method has strong anti-noise ability.

Opis:
This paper presents a dual inductor-fed boost converter with an auxiliary transformer and voltage doubler for sustainable energy power converters. The new topology integrates a two-phase boost converter and a dual inductor-fed boost converter. The energy stored and transferred by both inductors can attain a wide input-voltage and load range which uses a constant switching frequency, by controlling the time duration of the simultaneous conduction of the two switches. Among other current-fed type boost converters the presented topology is attractive due to the high voltage conversion ratio, less stress on the components and less switch conduction loss. To verify the feasibility of this topology, the principles of operation, theoretical analysis, and experimental waveforms are presented for a 1 kW prototype.

The research for novel power conversion topologies and the development of cutting-edge power component technologies are driven by the demand for renewable and much more efficient electricity generation, delivery, and conversion. Simulation and Analysis High Voltage Gain DC-DC Converter with Double Voltage Booster Switched Inductor for PV Applications are analyzed in this paper. Multilevel boost converter topologies recently reintroduced, are gaining popularity as a solution for industrial and transportation power systems because they enable the use of innovative, efficient, but relatively low voltage low-voltage devices at greater voltage and power levels. there is only one power switch on the converter that is planned here, three diodes, two capacitors, and two inductors to achieve ultra-high gain with better efficiency. High voltage gain, minimal switch stress, and the ability to lessen input-current ripple and capacitor voltage ripple are all benefits of the topology. When it switches complementary, the capacitors' ripple is reduced, which lowers the size requirement for the capacitors. A 12V, 500 watts prototype was analyzed, simulated and designed. at a duty cycle of 0.75 it is achieved high DC-DC gain i.e 19 and efficiency 93%. The practicality of the converter will be demonstrated by the close agreement between the analysis and simulation findings.

Opis:
A novel circuit topology of modified switched boost high frequency hybrid resonant inverter fitted induction heating equipment is presented in this paper for efficient induction heating. Recently, induction heating technique is becoming very popular for both domestic and industrial purposes because of its high energy efficiency and controllability. Generally in induction heating, a high frequency alternating magnetic field is required to induce the eddy currents in the work piece. High frequency resonant inverters are incorporated in induction heating equipment which produce a high frequency alternating magnetic field surrounding the coil. Previously this high frequency alternating magnetic field was produced by voltage source inverters. But VSIs have several demerits. So, in this paper, a new scheme of modified switched boost high frequency hybrid resonant inverter fitted induction heating equipment has been depicted which enhances the energy efficiency and controllability and the same is validated by PSIM.

The purpose of this paper is to propose a model of a novel quasi-resonant boost converter with a tapped inductor. This converter combines the advantages of zero voltage quasi-resonant techniques and different conduction modes with the possibility of obtaining a high voltage conversion ratio by using a tapped inductor, which results in high converter efficiency and soft switching in the whole output power range. The paper contains an analysis of converter operation, a determination of voltage conversion ratio and the maximum voltage across power semiconductor switches as well as a discussion of control methods in discontinuous, critical, and continuous conduction modes. In order to verify the novelty of the proposed converter, a laboratory prototype of 300 W power was built. The highest efficiency η = 94.7% was measured with the output power Po = 260 W and the input voltage Vin = 50 V. The lowest efficiency of 90.7% was obtained for the input voltage Vin = 30 V and the output power Po = 75 W. The model was tested at input voltages (30–50) V, output voltage 380 V and maximum switching frequency 100 kHz.

Opis:
Nowadays, there is a need to increase the continuous usage of the power electronic converters like AC-DC, DC–DC, and DC–AC based on various applications like mobile charge controller and telecom base station. Also, for power stability control, these converters are utilized in the renewable energy system (RES). The output cannot be stable for a longer duration due to the inappropriate switching pulse and continued usage of the converter. For resolving the above issues, the soft-switching technique is implemented in the proposed system for controlling both converter and inverter for proper energy stabilization during the continuous operation of devices. The main objective of this work is to improve the solar power system using high voltage gain DC / DC converter. Similarly, an inverter delivers the continuous AC power to the grid system without any fluctuations. The revolutionary substantial transformative control (RSTC) technique has been employed to monitor and control the converters used in this system. The additional advantage of this system is battery-based energy management, which is only utilized under necessary conditions. During the initial stage, RSTC will track the solar power, and it compares with the reference voltage and produces the appropriate pulse to the converter switch. Based on the switching pulse, the full-bridge converter (FBC) will also enhance the DC voltage by providing the constant voltage for the grid-connected inverter system. Secondly, the proposed RSTC controller will be monitoring voltage amplitude and frequency of grid power system. If any variation appears due to source power fluctuation, the controller will recognize it and automatically vary the pulse width modulation (PWM) of an inverter and compensate the grid power. The design analysis and operating approaches of the proposed converter are verified by MATLAB / Simulink 2017b. The performance analysis has been done with various parameters like total harmonics distortion (THD), steady-state error and converter efficiency.

Opis:
Conventional boost converters are widely used for connecting low-voltage power sources and inverters in motor control. However, a large filter capacitor bank is often used to reduce DC-link ripples that occur when an inverter is connected to a boost converter. Otherwise, significant voltage and current perturbations can impact on battery performance degradation and cause torque ripple, speed ripple and vibration in brushless DC (BLDC) motors. To suppress the converter’s DC-link ripple, this paper proposes a new control strategy for boost converter controller to generate low-ripple DC-link voltage or current at different motor speeds. In the proposed method, observers are designed to adaptively estimate the DC-link voltage and current harmonics. The harmonic terms are used as feedback signals to calculate the DC converter’s duty cycle. The entire control model is implemented on an embedded system, and its robustness is verified by simulation and experimental results that show the DC-link voltage and current ripples can be reduced by about 50% and 30%, respectively.

Opis:
The non-linearity in I-V characteristics of a PV panel requires to be operated at knee point to extract maximum power. In order to operate the panel at optimal point, maximum power point tracking (MPPT) algorithm is employed in the control structure. The main objective of MPP tracking is to keep the operation at knee point of I-V characteristics under varying condition of temperature and solar insolation. Under non uniform solar PV insolation falling on PV panels connected in series, a partial shading condition (PSC) occurs under cloud or shadow effects causes multiple power peak formation. The conventional MPPT methods fail to converge at global maximum power point (GMPP) under the PSC condition. Occurrence of these multiple peaks on characteristics of P-V makes tracking very difficult and requires integration of an efficient algorithm that differentiates between global and local maximum power point. This paper proposes a variable structure constant voltage method to overcome the problem faced by conventional MPPT methods. Moreover, quadratic boost converter has been taken for MPPT operation for increasing the effective gain of the converter. The effective operation of control algorithm has been validated in simulation results.
Na skutek nieliniowości charakterystyk I-U panelu fotowoltaicznego jego maksymalną moc uzyskuje się, gdy pracuje on w punkcie przegięcia. Aby panel pracował w optymalnym punkcie, w strukturze sterowania należy zastosować algorytm śledzenia punktu mocy maksymalnej (ang. maximum power point tracking – MPPT). Głównym celem śledzenia MPP jest utrzymanie działania panelu PV w punkcie przegięcia charakterystyki I(U) (w tzw. kolanie) niezależnie od zmian temperatury i nasłonecznienia. Pod wpływem częściowego zacienienia paneli fotowoltaicznych połączonych szeregowo (ang. partial shading conditio – PSC), np. z powodu zachmurzenia, na charakterystyce I(U) powstaje kilka punktów przegięcia. Konwencjonalne metody MPPT nie prowadzą do zbieżności w globalnym punkcie mocy maksymalnej (ang. global maximum power point – GMPP) w warunkach PSC. Występowanie kilku szczytów na charakterystyce P(U) bardzo utrudnia śledzenie optymalnego punktu pracy i wymaga użycia takiego algorytmu sterowania, który rozróżnia globalne i lokalne punkty mocy maksymalnej. W celu rozwiązania tego zagadnienia zaproponowano w artykule układ regulacji o stałym napięciu i zmiennej strukturze sterowania. Aby zwiększyć wzmocnienie napięciowe układu energoelektronicznego, zastosowano podwójny przekształtnik podwyższający napięcie. Skuteczne działanie algorytmu sterowania zostało potwierdzone wynikami symulacji.

Opis:
Boost converters are needed in many applications which require the output voltage to be higher than the input voltage. Recently, boost type converters have been applied for industrial applications, and hence it has become an interesting topic of research. Many researchers proposed different impedance source converters with their unique advantages as having a high voltage gain in a small range of duty cycle ratio. However, the thermal behaviour of the semiconductor devices and passive elements in the impedance source converter is an important issue from a reliability point of view and it has not been investigated yet. Therefore, this paper presents a comparison between the conventional boost, the Z-source, and the Y-source converters based on a thermal evaluation of the semiconductors. In addition, the three topologies are also compared with respect to their efficiency. In this study the results show that the boost converter has higher efficiency than the Z-source and Y-source converter for these specific voltage gain of 2 and 4. The operational principle, mathematical derivations, simulation results and final comparisons are presented in this paper.
