Abstract

The operating range of a zero-voltage switched inverter is typically constrained by the source and load variation. This paper adopts a variable turns ratio coupled magnetic type soft-switching inverter for a wide-range source and load adaptability. The operating principle and design guideline are described in detail. Design examples have been verified with computer simulation and hardware implementation. Experimental results of a 120-kW hardware prototype are presented to show superiority of the proposed soft-switching inverter design and significant reduction on loss and dv/dt
