The invention relates to a discharge control device for a vehicle high-voltage system. The discharge control device comprises a discharge circuit formed by connecting a discharge resistor and an electronic switch in series; the voltage acquisition unit is used for acquiring voltage values at two ends of the bus capacitor in real time; the control unit is configured to judge whether a vehicle high-voltage system needs to be discharged or not on the basis of at least one of a sampling signal received from the voltage acquisition unit, a first communication signal received from the safety airbag module and a second communication signal received from the vehicle control unit; and when it is determined that the vehicle high-voltage system needs to be discharged, operation of the driving chip and/or the electronic switch is selectively controlled, so that the vehicle high-voltage system enters a corresponding discharging mode. The invention also relates to an electrically driven inverter comprising the discharge control device.

    本申请涉及一种用于车辆高压系统的放电控制装置,包括:由放电电阻和电子开关串联构成的放电电路;电压采集单元,用于实时采集所述母线电容两端的电压值;以及控制单元,其配置为基于从所述电压采集单元接收的采样信号、从所述安全气囊模块接收的第一通信信号以及从所述整车控制器接收的第二通信信号中的至少一者判断是否需要对车辆高压系统进行放电,并且在确定需要对该车辆高压系统进行放电时选择性地控制所述驱动芯片和/或所述电子开关的操作,以使所述车辆高压系统进入相应的放电模式。本申请还涉及一种包括该放电控制装置的电驱逆变器。
