摘要： A bi-directional AC/AC converter is designed to provide improved AC/AC power conversion along with reduced switching losses, reduced harmonic distortion and improved power factor. The converter is characterized by bi-directional switches comprising IGBTs that are selectively turned ON to generate an output AC voltage having a frequency in the range of 50 Hz to 30 kHz. The conduction of IGBTs for each phase of a three phase supply is controlled by a control circuit provided therein.
