Abstract	This work presents a novel battery charger with a zero-voltage-transition (ZVT) pulse-width-modulated (PWM) boost converter that decreases switching losses and attains high charging efficiency. The main switch in the proposed battery charger is conducted under zero voltage and the boost diode is cut off under zero current. Switching is completed under the resonance condition. The proposed battery charger with soft-switching technology has much higher efficiency, lower switch stress and electromagnetic interference (EMI) compared with battery chargers with traditional boost converters. This study utilizes the PWM control mode for switching two active switches. The equations employed to determine circuit parameters are derived from equivalent circuits. Experimental results demonstrate the theoretical effectiveness of the proposed battery charger. The practical average charging efficiency of the proposed battery charger is 91.25%.
