Abstract

The paper presents an isolated bi-directional half bridge CLLLC converter for electric bike charging application. Phase shift control strategy has been proposed to charge and discharge the battery as well as to achieve the required voltage gain. A simplified closed loop control has been implemented and the performance of the controller as well as the converter has been verified in simulations. The experimental realization has been done and the performance of the converter has been tested in both (charging and discharging) power transfer directions. The highest efficiency of 96.2% has been achieved at 24V of battery voltage and 2A of charging current.
