APPARTUS FOR DISCHARGING VOLTAGE OF DC LINK CAPACITOR IN MOTOR DRIVING DEVICE

摘要

Disclosed is a DC link capacitor discharge device. A DC link capacitor discharging device according to an embodiment of the present invention includes a DC link capacitor installed in a DC link of a vehicle battery, a discharge resistor connected in parallel with the DC link capacitor, a switching element for a discharge resistor connected in series with the discharge resistor, and a discharge resistor. And a microcontroller for turning on or off the switching element, and the switching element for discharge resistance is turned on by a low-level switching signal output from the microcontroller.
