SYSTEM AND METHOD FOR PROTECTING HIGH-VOLTAGE COMPONENTS

The invention relates to a system and method for protecting high-voltage components. A power distribution system for a vehicle includes a first contactor configured to selectively couple a traction battery and an inverter that operates an electric machine via switch control. The system includes a second contactor that selectively couples an electrical load and the traction battery. The first contactor and the second contactor are closed to operate the vehicle. The system includes a controller programmed to, in response to loss of the inverter switching control, disconnects the first contactorbut not the second contactor to isolate the inverter from the traction battery. 本公开涉及用于保护高电压组件的系统和方法。种用于车辆的配电系统包括第接触器，第接触器被配置为选择性地连接牵引电池和逆变器，所述逆变器经由开关控制来操作电机。所述系统包括选择性地连接电气负载和牵引电池的第二接触器。第接触器和第二接触器闭合以操作车辆。所述系统包括控制器，所述控制器被配置为响应于逆变器开关控制的失去，断开第接触器，但不断开第二接触器以将逆变器与牵引电池隔离。
