High-efficiency bidirectional DC-DC converter with high voltage conversion ratio
This paper proposes a high-efficiency bidirectional dc-dc converter with high voltage conversion ratio for low voltage energy storage devices. For a step-up operation, the proposed converter operates with a high step-up voltage conversion ratio. It has low voltage stresses of the power switches at the low voltage side. It also has low switching losses of the output diodes at the high voltage side. For a step-down operation, the proposed converter operates with a high step-down voltage conversion ratio. It features zero-voltage switching of power switches at the high voltage side. At the low voltage side, a current doubler rectifier reduces the current ripples. Simulation verifications and experimental results are presented to verify the operation of the proposed converter.
