Abstract

This paper presents a high voltage waveform generator capable of generating waveforms composed of multiple sinewaves whose frequencies are integer multiples of a fundamental frequency (harmonics). The proposed approach allows synthesis of inverter pulse-trains with a large number of controlled harmonics, called selective harmonic generation. These waveforms are produced with a GaN inverter and tested for their utility in generating ozone in a dielectric barrier discharge reactor, obtaining 193 ppm/W (parts per million per watt) with a 0.5 lpm (litre per minute) flowrate of dry air as the feedstock.
