MATLAB SIMULATION OF A DC-AC-DC CONVERTER WITH ZERO-VOLTAGESWITCHING

A full-bridge dc–dc converter is proposed featuring zero-voltage-switching (ZVS) of active switches over the entire conversion range. In contrast to conventional techniques the stored energy in the auxiliary inductor of the proposed converter is minimal under full load condition and it progressively increases as the load current decreases. Therefore, the ZVS operation over the entire conversion range is achieved without significantly increasing full load conduction loss making the converter particularly suitable in applications where the output is required to be adjustable over a wide range and RL load , and variable load for practical is to be calculated.
