Method and apparatus for monitoring a high-voltage electrical circuit including a discharge circuit
Abstract:
A high-voltage discharge circuit diagnostic system includes a high voltage DC link with a positive DC link and a negative DC link, a first resistor selectably connectable between the positive DC link and the negative DC link, and a second resistor connected between the positive DC link and the negative DC link. A control module connects the first resistor between the positive DC link and the negative DC link until the high voltage DC link discharges to a first voltage after which the control module disconnects the first resistor from between the positive DC link and the negative DC link to permit continued discharge of the high voltage DC link through the second resistor to a second voltage through an elapsed time period. The control module diagnoses a fault in the second resistor based upon the first voltage, the second voltage, and the elapsed time period.
Abstract(Chinese):

高压放电电路诊断系统包括具有正直流链路和负直流链路的高压直流链路，可选择地在正直流链路和负直流链路之间连接的第一电阻器和连接在正直流链路之间的第二电阻器 链路和负DC链路。 控制模块连接正直流链路和负直流母线之间的第一电阻，直到高压直流母线放电到第一电压，之后控制模块从正直流链路和负直流母线之间断开第一个电阻，以允许 通过第二电阻将高压直流母线继续放电至经过时间段的第二电压。 控制模块基于第一电压，第二电压和经过的时间周期来诊断第二电阻器中的故障。
