摘要：
The paper presents an improved method of generating a three-phase stepped-voltage waveform using ten thyristor power switches. In the proposed method, it is possible to generate one step for every 20 degree of the voltage waveform on all the phases. The waveform has a total harmonic distortion of about 10% and the predominant harmonics are the 17th and 19th. This is possible by a unique method of magnetic coupling between a 120 degree conduction three-phase bridge inverter and a triple frequency single-phase bridge inverter. The theoretical results are in close agreement with experimental results.
