Special designed universal power switching generator simplifies 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 which could simplifies their studies. The device is capable of generating the selected waveforms which can deliver a 30W maximum 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.
