Abstract

To address the complex topology of auxiliary resonant commutated pole inverters and the large current stress of auxiliary switches, this paper proposes an auxiliary resonant commutated pole soft-switching inverter with a simple topology. The proposed inverter not only reduces the current stress of the auxiliary switches and the loss caused by the reactive energy conversion in the circuit but also simplifies the topology of the auxiliary commutated circuit, reduces the cost of the inverter, and improves the reliability of the inverter. The inverter is suitable for small and medium power applications. Under the proposed modulation strategy, the operation principle of the inverter, the conditions of soft-switching realization, and the optimal parameter design method are analyzed in detail according to the equivalent circuit diagrams in different operating modes. Finally, a 10-kW, 16-kHz prototype is fabricated using insulated gate bipolar transistors (IGBT) as switches, and the effectiveness of this inverter is verified through experiments.
