Abstract

The Selective Harmonic Elimination (SHE) for Current Source Inverter (CSI) fed drives is presented in this paper. The PWM patterns for selective harmonic elimination are generated using a unified approach. The conventional methods cannot handle more than a few harmonics as the independent chop angles are restricted to 30°. In this work, a combination of chops as well as short circuit pulses are utilized to selectively eliminate lower order harmonics with minimum switching frequency.
