- Abstract
A zero-voltage and zero-current switching full bridge converter with series resonance tank is presented in this study. This converter is based on standard full bridge topology and a series capacitor is added in the primary side to reset the leakage inductance current without any additional auxiliary circuit. Leakage inductance of the transformer is used as the resonance inductance. Using series resonance tank and applying control pulses with fix frequency, zero-voltage switching for leading leg and zero-current switching for lagging leg is achieved. The output power is controlled using phase shift technique. In the proposed converter, soft-switching condition is attained for wide range of load variation. Due to its high performance and minimum additional components with respect to regular converter, this converter can be applied for medium to high-power applications. Topology and operating modes are discussed and the validity of theoretical analysis is verified by prototype experimental results.
