一种单向单级三相软开关隔离式DC-AC变换器

This paper presents a novel single-stage soft-switched high-frequency-link three-phase dc-ac converter topology. The topology supports unidirectional dc to ac power flow and is targeted for applications like grid integration of photovoltaic sources, fuel cell, etc. The high frequency magnetic isolation results in reduction of system volume, weight, and cost. Sine-wave pulsewidth modulation is impl...
