Disclosed is a linked capacitor discharge circuit with temperature control. In at least some implementations, a discharge circuit for an electric vehicle includes a link capacitor, a resistive load, a discharge switch coupled to the link capacitor and to the resistive load such that when the discharge switch is closed, the link capacitor is coupled to the resistive load to enable discharge of the link capacitor, and a discharge interrupt component. The discharge interrupt assembly has a sense resistor and a temperature circuit connected in series with the resistive load. A temperature circuit has an input and an output connected to the sense resistor, and a discharge interrupt circuit is responsive to a voltage at the output of the temperature circuit to turn off the discharge switch when the voltage from the temperature circuit is above a threshold.
具有温度控制的链接电容器放电电路。在至少一些实现中,用于电动车辆的放电电路包括链接电容器、电阻性负载、耦合到链接电容器并且耦合到电阻性负载的放电开关,使得当放电开关闭合时,链接电容器耦合到电阻性负载以使能链接电容器的放电,以及放电中断组件。放电中断组件具有与电阻性负载串联连接的感测电阻器和温度电路。温度电路具有连接到感测电阻器的输入和输出,并且放电中断电路响应于温度电路的输出处的电压,以在来自温度电路的电压高于阈值时断开放电开关。
