Abstract
This letter proposes a novel space vector pulsewidth modulation scheme for three-phase current source inverter. In the proposed switching, one of upper switches and one of lower switches are always on-state, so there is no overlap between high-frequency switching signals. Therefore, the inverter can improve the quality of output waveforms and efficiency. In addition, the number of switching is reduced with the help of sensed line-to-line voltage. A 1-kW prototype was built and tested to verify the performance of the proposed scheme.
