Abstract

A novel full-bridge converter suitable for low-voltage high-current output applications is proposed. It realizes ZVS for all switches over the entire load range with the use of voltage complementary auxiliary network on the primary side. A current-doubler rectifier is adopted on the secondary side which has no duty cycle loss and no secondary voltage spike. The operation principle and characteristic of the converter are discussed in detail. The design method of key parameters is given. The performance of the proposed converter is verified by experimental results.
