Research on an active double auxiliary resonant commutated pole soft-switching inverter

Aiming at overcoming the problem that the auxiliary switches in an improved auxiliary resonant communicated pole (ARCP) inverter may not realize zero-voltage-switching (ZVS) turning off in practical application if there is parasitic inductance in the wiring process, this paper proposes an active double ARCP inverter topology. In novel topology, the auxiliary capacitor and the auxiliary switch are in parallel closely. This connection avoids the influence of parasitic inductance in the wire, and it ensures the auxiliary switch to realize ZVS turning off reliably. The proposed inverter not only inherits all advantages of the improved ARCP inverter, but also improves its reliability. According to the equivalent circuits in different operation modes, this paper analyzes the circuit operation principle and soft-switching implementation condition. Finally, a 10 kW 16 kHz double ARCP inverter prototype with insulated gate bipolar transistor-based switches has been built. Experimental results are given to demonstrate the validity and features of the proposed inverter.
