PSpice model - Opis:
- The renewable energy sources or energy storage devices deliver output voltage at the range of around 12 VDC to 48 VDC. In order to obtain at least 350 VDC needed for direct to alternating current conversion the DC/DC power converter should demonstrate significant voltage gain and power conversion efficiency as high as possible. To obtain such level of output voltage at low input voltages transistors of the boost converter must operate with high currents. High efficiency and high voltage gain can be achieved with parallel combination of two or more isolated step-up converters. The converters operate synchronously and in phase, using the same control signals. Balancing transformers are used to ensure the synchronization and equal distribution of current between the power levels. They provide equal distribution of significant input current to a number of smaller current loops. This feature alongside with the use of power MOSFETs with low channel resistance and silicon carbide (SiC) Schottky diodes will reduce losses within the converter and increase the efficiency of entire energy conversion system. This paper presents PSpice simulation results of partial parallel isolated DC/DC boost converter with voltage doubler. In presented circuit high voltage gain and high conversion efficiency were achieved.
