| الوصف: | This paper presents the elimination of common mode (CM) conducted emissions in three-phase four-wire four-pole inverters connected to an AC distribution bus and operating in grid-following mode. Two novel control strategies are proposed and compared to the CM emission limits in the military standard 461G. Delta modulation and model predictive control both demonstrate elimination of the common mode voltage at the output of the three-phase four-pole inverter and the ability to meet the military standard’s requirements without a CM choke. The differential mode performance is comparable to that of three-dimensional space vector modulation, which does not cancel CM emissions. A physics-based model of the system was developed using state space equations to simulate the conducted emissions that can be expected with the two proposed methods. As the proposed methods result in increased switching frequency, wide bandgap devices were used to build a laboratory prototype, which successfully validate the simulated results. |
