Abstract :

In this paper, a new two-input converter with zero voltage switching for green energy hybrid systems is presented. In the proposed converter, a new auxiliary circuit is used to create zero voltage switching with the least number of auxiliary elements. The auxiliary circuit not only provides zero voltageswitching conditions, but also absorbs the energy of the leakage inductance and prevents voltage spikesacross the main switches. On the other hand, the use of coupled-inductors also increases the gain of the converter and greatly reduces the voltage stress on the switches. The proposed converter has been designed with a 120 watts power and simulated in PSICE software, and also a prototype has been made to prove the theoretical analysis of the circuit.
