A Phase-Shift Control Method of Triple-Active-Bridge Converter for Reducing Power Loss Under Light Load Condition

This paper presents a phase-shift control method of triple-active-bridge converter for distributed power supply systems with multiple batteries. The experimental results show that the reactive through transformer can be suppressed under wide range conditions. proposed improves light load loss at 500W by approximately 30% compared to conventional method. In addition, according power-transmission characteristics method, applications in which voltage source connected an input port is attached and detached, demand adjusted between each output while gradually lowering charge utilizing charging operation. Therefore, continue operate regardless attachment detachment port-voltage source.
