An exemplary dual power inverter module includes a DC link capacitor electrically connectable to a source of high voltage direct current (DC) electrical power. A first power inverter is electrically connectable to the DC link capacitor and configured to convert high voltage DC electrical power into three-phase high voltage alternating current (AC) electrical power, and is configured to supply the three-phase high voltage AC electrical power to a first electric motor. A second power inverter is electrically connectable to the DC link capacitor, configured to convert high voltage DC electrical power into three-phase high voltage AC electrical power, and configured to supply the three-phase high voltage AC electrical power to a second electric motor. A common controller is electrically connectable to the first power inverter and the second power inverter. The common controller is configured to control the first power inverter and the second power inverter. The dual power inverter module can prevent an increase in weight and energy consumption.

    예시적인 이중 전력 인버터 모듈은 고전압 직류(DC) 전력의 소스에 전기적으로 접속가능한 DC 링크 커패시터를 포함한다. 제1 전력 인버터는 DC 링크 커패시터에 전기적으로 접속가능하고, 고전압 DC 전력을 3-상 고전압 교류(AC) 전력으로 변환하도록 구성되고, 3-상 고전압 AC 전력을 제1 전기 모터에 공급하도록 구성된다. 제2 전력 인버터는 DC 링크 커패시터에 전기적으로 접속가능하고, 고전압 DC 전력을 3-상 고전압 AC 전력으로 변환하도록 구성되고, 3-상 고전압 AC 전력을 제2 전기 모터에 공급하도록 구성된다. 공통 제어기는 제1 전력 인버터 및 제2 전력 인버터에 전기적으로 접속가능하다. 공통 제어기는 제1 전력 인버터 및 제2 전력 인버터를 제어하도록 구성된다.
