摘要: Single-stage switching transfer functions of force-commutated frequency changes are generalized for an arbitrary number input/output phases. Then, practical modulation methods and their mathematical analysis presented. The proposed techniques mathematically justified were implemented using microprocessors. quality the generated waveforms is analyzed to develop proper improve waveforms. Harmonic force commutated direct changers also described. >
