Opis:
This work focuses on the concept of operation and possibility of using a tuned inductor in electrical power systems with adaptive features. The idea presented here for the operation of the inductor is a new approach to the design of such devices. An example of a power adaptive system is a device for improving the quality of electricity. The negative impact of nonlinear loads on the operation of a power grid is a well-documented phenomenon. Hence, various types of “compensators” for reactive power, or for both reactive and distortion power, are used in electrical systems as a preventive measure. The concept of an inductor presented here offers wider possibilities for power compensation in power supply systems, compared to traditional solutions involving compensators based on fixed inductors. The use of the proposed solution in an adaptive compensator is only one example of its possible implementation in the area of power devices. In this work, we discuss the structure of the compensator, the basic aspects of the operation of the inductor, the results of simulation studies and the results of measurements obtained from a prototype.

Opis:
In the paper the novel universal motor driver using three different modulation method of output waveform has been presented and discussed. It should be noted that in today’s world, most of driver of electrical motors are consist of four or six transistors forming appropriate bridges. Appling specified modulation methods enable to drive both single- and three-phase induction and synchronous motors of any kind. The construction of typical transistor bridge that consists of six transistors can be also used to control the direct current motors by switching off one of the pairs of transistors. In this paper the process of construction of universal motor driver has been presented, in which has been implement the modified method of Sinusoidal Pulse Width Modulation (SPWM), Space Vector Pulse Width Modulation (SVPWM) and also the basic Pulse Width Modulation (PWM) for DC motors. The fundamentals of applied modulation algorithms have been discussed and basic equations have been shown. The developed motor controller has been used to power three different types of motors, single-phase induction motor, threephase induction motor and magnetoelectric DC motor. The results of the conducted research have been reported in this work.
