Three-phase multi-switch Buck type rectifier circuit

Three-phase multi -switch Buck type rectifier circuit : The DC side reactor generally requires a large amount of power. Due to the characteristics of current-mode converters, an AC-side input LC filter is usually necessary to improve the current waveform and power factor. This circuit topology is more suitable for space vector modulation and has a voltage-reducing effect. The disadvantage is that the large inductor on the DC side has a large internal resistance and consumes a lot of power, resulting in its efficiency being slightly lower than the six-switch Boost type.
