The paper proposes airborne quadruple-three-phase power train architectures featuring low electromagnetic emissions and reduced dc-link ripple current. The paper first identifies the conflict of achieving minimized common-mode voltage (CMV) and dc-link ripple current jointly using a dual three-phase drive system. Then drive systems consisting of four three-phase winding sets are proposed. It shows that in contrast to the dual three-phase drive with proper modulation methods and winding displacements, the CMV and ripple current reach their best cancellation simultaneously. The proposed system and related operating methods ideally achieve complete common-mode voltage (CMV) cancellation and up to 67% dc ripple current reduction compared to the single-three-phase solution. The superior cancellation feature results in a six times smaller dc-link capacitor and ten times smaller electromagnetic interference (EMI) filter for a ±500 V, 250 kW power-train inverter design. A 250-kW quadruple three-phase high-altitude prototype for electrified aircraft was designed based on the proposed architecture using SiC Mosfets. Experimental results are provided to validate the approach.
