Analysis and Design of a Single-Phase Half-Bridge Rectifier/Inverter with an Active Resonant DC Bus Voltage Balancer

This paper presents the analysis and design of the single-phase half bridge rectifier with an active voltage DC bus balancer (ARVB). Impact of the power ripple on the DC bus of the ordinary rectifier/inverter and the rectifier/inverter with the ARVB is examined. It will be shown that with the ARVB, the volume and size of the DC bus; hence the converter can be significantly reduced, since the ARVB eliminates fundamental and the most significant component of the DC bus current.
