SYMMETRIC AND BIDIRECTIONAL RESONANT CONVERTER

摘要

PURPOSE: A symmetric and bidirectional resonant converter is provided to obtain a CLLC resonance structure from any directions by having a symmetric and identical circuit structure in both directions regardless of the flow of current in high or low pressure. CONSTITUTION: A first resonance circuit, a transformer(TF), and a second resonance circuit are combined between a first bridge circuit and a second bridge circuit. A first resonance circuit is connected to both output ends of a first bridge circuit. A first resonance circuit includes a first inductor(L1) and a first capacitor(C1). A second resonance circuit is connected between the both input ends of a second bridge circuit. A second resonance circuit includes a second inductor(L2) and a second capacitor(C2). A voltage direction is changed into a constant cycle through a first bridge circuit and is inputted into a first resonance circuit. A rectified resonance voltage is generated through a second bridge circuit. A rectified restoration voltage is generated through a first bridge circuit.
