Issues on Simulations of Inverter Power Supply

Abstract

The modern supply for non-industrial equipment, unlike the industrial power supply installations, must have specific parameters (voltage and frequency). Some modern devices, as the converter – inverter system with static commutation elements, can be used in order to obtain these parameters. The role of the converter in this system is to convert the alternative current of the industrial supplying device to a continuous current; with the help of the inverter the voltage is converted back to alternative voltage.This paper presents the alternative – continuous current conversion bridge (the converter), the continuous – alternative conversion bridge (the inverter) having different switching elements and the PWM command signal generation methods of the semiconductor elements by using the “Matlab–Simulink” graphical environment. The system, converter-inverter, has been simulated for a specific parameters R, L, C. These parameters have been obtained after a designing calculation for a universal load. The simulations presented use the static switching device as optimal for a proper behaviour of the inverter in the case of the given charge.
