“…The works in [13,14] are two famous auxiliary resonant commutated pole (ARCP) inverter topologies which were, respectively, proposed by W. Mcmurray and R. W. De Doncker originally, who initiate the research on ARCP inverters. Subsequently, many improved ARCP inverters were proposed [15][16][17][18][19][20][21][22][23]. However, these topologies need either two bulky capacitors or complex coupled inductors, or transformers with corresponding magnetic flux reset circuits.…”

This study presents a double auxiliary resonant commutated pole (ARCP) inverter topology and modulation strategy. In the proposed inverter, the zero-voltage-switching (ZVS) turn-off of auxiliary switches influenced by parasitic circuit elements from the wiring process can be avoided. It is assured that the auxiliary switches achieve ZVS turn-off reliably. Hence, the reliability of the ARCP inverter is improved, especially in high-power application. According to the equivalent circuits in different operation modes under the proposed modulation strategy, the working principle, softswitching implementation condition, and parameter design procedure of the proposed inverter are analysed successively in this study. Finally, a 10 kW, 16 kHz double ARCP inverter prototype is built. Experimental results are given to demonstrate the validity of the proposed inverter.
