The Three-Phase Current-Fed Inverter applying the One-Phase Modulation Principle that was proposed for the Three-Phase Voltage-Fed Converter

Abstract

The one-phase switching method (one-phase modulation) for the three-phase voltage-fed inverter was proposed. The author presents an applying method of the one-phase modulation for the three-phase current-fed inverter. This letter describes a comparison of the switching patterns for the current-fed inverter between the conventional methods and presented method. To prove the validity of the presented method, the simulated results are shown.
