Efficient utilization of transformer by reducing leakage current using bidirectional converter [articol]

Abstract

This paper deals with efficient use of transformer by reducing switch loss, large gaining force, bidirectional converter with fragile trading with high change proportion, and delicate start-up ability. Better utilization of transformer can be done by reducing leakage current. An isolated bidirectional full-bridge dc–dc converter has been proposed with high conversion ratio, high output power, and soft start-up capability. The current variation between leakage inductance of the isolation transformer and current fed inductor will produce voltage spike is managed by fly back converter. The user of a capacitor, fly back convertor and through active switches a diode can reduce current streaming at the current fed side. Our proposed attains better performance compared to LCC-T Resonant Converter with ZCS.
