일 실시예에서, 전기 추진 시스템은 항공기의 하나 이상의 프로펠러를 구동하도록 구성된 전기 모터, 직류(DC) 모선 전압을 안정화하도록 구성된 커패시터, 커패시터에 결합되고 제1 펄스 폭 변조(PWM) 벡터에 대한 응답으로 전기 모터의 제1 스테이터 권선 세트를 구동하기 위해 DC 모선 전압을 교류(AC) 전압으로 변환하도록 구성된 제1 인버터 회로 및 커패시터에 결합되고 제2 PWM 벡터에 대한 응답으로 전기 모터의 제2 스테이터 권선 세트를 구동하기 위해 DC 모선 전압을 AC 전압으로 변환하도록 구성된 제2 인버터 회로를 포함한다. 제1 PWM 벡터 및 제2 PWM 벡터는 실질적으로 동일하면서 반대인 벡터이다.
In one embodiment, an electrical propulsion system includes an electrical motor configured to drive one or more propellers of the aircraft, a capacitor configured to stabilize a direct current (DC) bus voltage, a first inverter circuit coupled to the capacitor and configured to convert the DC bus voltage to alternate current (AC) voltages to drive a first set of stator windings of the electrical motor, in response to a first pulse width modulation (PWM) vector, and a second inverter circuit coupled to the capacitor and configured to convert the DC bus voltage to AC voltages to drive a second set of stator windings of the electrical motor, in response to a second PWM vector. The first PWM vector and the second PWM vector are substantially equal and opposite vectors.
