Abstract

In this paper, we designed a soft switched synchronous boost converter, which can perform discharging the battery, is simulated, and experimented designed. The converter operates synchronous operation to increase efficiency of the converter. The converter has very small switching losses because of its soft switching characteristics. In this paper, battery discharger with a switching frequency of 100 kHz have been designed. The designed converter also simulated and experimented to prove the converter's characteristics during synchronous operation. The simulated and experimental results have confirmed that the battery discharger had soft switching characteristics. In addition, the experimental results confirm that the converter has high efficiency characteristics. The efficiency of the circuit exceeds 97%, the efficiency of soft switched synchronous boost converter is at least 6% higher than that of conventional PWM boost converter.
