Abstract

To simplify the complexity of the system, a bi-directional DC-DC converter based on half-bridge current-double rectifier (HBCDR) topology was studied to replace the two unidirectional DC-DC converters in the original design. The operation principle was analyzed in detail. And in case of abrupt power-off of control unit, high voltage spike would be found on the power switches. Measures that inductors were replaced with specific transformers were put forward to restrict possible destruction and the design rule was described. Simulation was performed and waveforms were analyzed. A prototype was done and results were presented. It was proved that the proposed converter could effectively carry out the constant-current charging and discharging of battery cell.
