摘要
This study presents an auxiliary cell that can be applied to the single-phase full-bridge inverter. The cell employs two auxiliary switches, two auxiliary diodes, one resonant capacitor, and one resonant inductor, as it can be used in both inverter legs so that switching losses are minimised, thus implying increased efficiency and low electromagnetic interference levels. Three possible configurations are investigated and theoretical analyses are carried out. Besides, the control strategy provides nearly sinusoidal output voltage with reduced harmonic distortion. Experimental results are presented and discussed to validate the proposal.
