A Bi-directional KY Converter is designed for applications such as electric vehicles, battery energy storage systems, and renewable energy integration, where power must flow efficiently in both directions. It can charge the battery or supply power from the battery by adjusting the PWM-controlled switches. The converter provides high voltage conversion, smooth battery current, high efficiency, and simple control. A 50 W prototype was developed and tested using a DSP controller, demonstrating reliable energy transfer.
