Special designed universal power switching generator for power electronics studies

Abstract

This paper presents a specially designed power switching generator device that produces 4 types of waveforms; square-wave, sinusoidal PWM, quasi-sinewave or multilevel and high-frequency DC pulses with a total of 14 different distinctive characteristics. The generator is exceptionally a useful tool to the students and researchers that dedicate themselves primarily in power electronics areas. The device is capable of generating the selected waveforms which can deliver a maximum 30W of power into a particular load. It is highly useful in harmonics analysis of inverters, true RMS measurements, switching devices driving signals, high-frequency switching transformer designs and filtering components for selective harmonics elimination.
