Abstract

Aiming at the existing technical defects, this paper proposed a high-boost single-stage inverter（VMC-qZSI）, which uses voltage multiplier units of DC-link and shoot-through state of inverter-link to realize dual degree of freedom adjustment of the AC output voltage by the coupled-inductor turns ratio n and shoot-through duty cycle D. A high voltage gain can be obtained when the D is small. The working mode of the new toplogy, voltage and current relationship between each component, and the comparison of the total switching power of three phase bridge type inverters are, described. On this basis, the relationship between the boost ratio and the efficiency of the inverter under the parasitic conditions is deduced. An 850 W prototype was built in the laboratory to verify the validity of the proposed inverter. Experimental results prove the validity and feasibility of the proposed inverters.
