<p>The traditional auxiliary resonant pole inverter produces circulating current after the resonance process. When the switching period is short or the duty ratio approaches its limit, both the auxiliary and main switches can barely achieve soft switching. To address the issue, this article proposes a three-phase soft-switching resonant pole inverter with circulation suppression capability. When the inverter enters the dead-time state, the auxiliary circuit begins to resonate, causing the voltage across the switches to drop to zero. This enables the main switches to operate under zero-voltage conditions and the auxiliary switches to function with zero-current characteristics. Furthermore, the main advantage of the proposed circuit is that once resonance ends, the circulating current is quickly absorbed, ensuring zero-current-switching (ZCS) for the auxiliary switches and zero-voltage-switching (ZVS) for the main switches. In this article, a 3&#xa0;kW prototype is developed, and both simulation and experimental verifications were carried out. Experimental findings show that the switching device operates in a soft-switching mode, and the circuit structure can improve the soft switching range of the inverter.</p>
