Abstract:	This work presents a novel highly efficient andlow-stress battery charger with a resonant switch converter—based on resonance and zero-voltage-transition soft-switchingtheory—that reduces defects associated with high voltage and highcurrent stresses caused by the resonance of traditional resonantcircuits. The novel battery charger meets the requirement thatall circuit components must operate with zero-voltage switching.Experimental test results indicate that the proposed batterycharger reduces the temperature of an active power switch, andswitching losses are less than those obtained using a traditionalpulsewidth-modulation converter as a battery charger.
