Numerous Z-source three-phase inverters are developed for realizing higher voltage gain which are suitable to use in hybrid electric vehicle to drive the electric machine. However, higher voltage and current stress of the passive elements and semiconductor devices are the major limitations of the reported Z-source inverters. In this article, a new quasi-switched boost three-phase inverter is proposed which has the following features: 1) very low continuous input current; 2) reduced voltage stress; 3) reduced current stress; 4) shoot through immunity; 5) single stage voltage conversion from dc to ac; and 6) improved output voltage quality by utilizing higher modulation index. The operation, steady-state analysis, and design guidelines for the proposed converter are discussed in detail. To prove the feasibility of the proposed inverter, a comparative analysis is also presented with the state-of-the-art converters. An experimental setup is designed on printed circuit board and tested for 400 W power rating.
