Summary:In this paper, novel unidirectional auxiliary resonant commutated pole is proposed to improve the performance of the zero-voltage soft-switching inverter. The proposed circuit keeps the advantages of the original soft-switching inverter, while providing more effective resetting capability in magnetizing current. Based on the advanced reset mechanism, auxiliary switches operate under a complete zero-current condition. The operating principle and steady-state analysis are presented theoretically, according to its operating modes. Accordingly, it proves the fact that the proposed unidirectional auxiliary resonant commutated pole breaks an unwanted magnetizing current loop effectively. The performance of the proposed circuit is verified by several simulation results under a 3KW load condition.
