چكيده فارسي :
In this paper a new bidirectional three level converter with soft switching operation and high efficiency is proposed. In the proposed converter by means of using two resonant LC elements soft switching operation for all the semiconductor elements are obtained. Also three level structure of the proposed converter caused lower voltage stress for all of the switches. Soft switching conditions is provided without auxiliary switch, which implementation of control circuit is simple. To justify the analysis, a prototype converter is designed, simulated and finally practically implemented. Simulation and experimental results have shown that the proposed converter operates under zero voltage switching condition and with these results the proposed converter has achieved the efficiency of 98%.
