Abstract
An electric power system has a power inverter system with a quasi-resonant circuit (QRC), and a controller, and couples a DC power supply to an electric machine. The power inverter system includes a positive inverter bus and a negative inverter bus; first paired switches; a positive DC bus terminal; and a negative DC bus terminal. The QRC includes an inverter inductance device, a capacitor, a first bus switch, and a second bus switch. The inverter inductance device and the second bus switch are arranged in series between the positive inverter bus and the first switch node, and the first bus switch is arranged between the positive DC bus terminal and the positive inverter bus. The controller is configured to control the QRC to generate an alternating current in the DC power supply.
