Abstract

A full-bridge bi-level inverter using a quasiresonant circuit DC-link to implement soft-switching is presented in this paper. It is demonstrated that the zero average current error algorithm digital time control can provide a suitable interface between the quasi-resonant circuit DC link and the inverter. Experimental results for a low power single-phase current-controlled inverter are documented, including quasi-resonant circuit waveforms, inverter waveforms and electromagnetic interference spectral characteristics
