Abstract

Conventional dual half-bridge converter has been previously shown to have advantages in low voltage and high current input applications. This characteristic is suited to photovoltaic application or battery application likes energy storage system (ESS) or uninterruptible power supply (UPS). However, conventional dual half-bridge converter cannot charge the battery because the power flow is one-way. Also, when switches are turned off, high voltage spikes occur by parasitic inductance. To solve this problem, a DC/DC converter which can operate in bi-direction and eliminated voltage spikes are proposed in this paper. Also proposed converter is operated under zero voltage switching (ZVS) condition. In this paper, operation principles and design method of proposed converter are described. These are verified by PSIM simulation and experimental results.
