Abstract

This paper introduces a novel bidirectional converter utilizing the switched inductor technique and incorporating a single magnetic component. The proposed converter is designed to optimize performance by ensuring that the voltage stresses on all of the switches remain below the voltage on the high side. This distinctive advantage over converters with higher voltage stresses contributes to enhanced reliability and efficiency in power electronic systems. To evaluate the efficiency of the proposed converter, a 200 W prototype is meticulously designed and implemented. This experimental setup serves as a platform for performance validation and analysis, shedding light on the practical implications of the proposed bidirectional converter. This contributes to the growing body of knowledge in bidirectional converters and addresses the practical challenges associated with voltage stresses in such systems.
