Abstract :
A novel single-to-three-phase power converter that allows a smaller smoothing capacitor in the DC link is proposed. Large smoothing capacitors are conventionally required in such converters to absorb power ripple at twice the frequency of the power supply. The proposed topology consists of an indirect matrix converter and an active snubber to absorb the power ripple, and does not require a reactor or large smoothing capacitor. The fundamental operations of the proposed converter are confirmed through simulations and experiments.
