A traction powertrain system of an electrified vehicle includes a power electronics module and a controller. The power electronics module, such as in the form of an inverter, is configured to drive a traction motor with power from a traction battery via a DC-link capacitor. The controller has an on-board power source, such as in the form of a super capacitor. The controller is configured to, in response to detecting an event in which the DC-link capacitor is to be discharged, use power from the on-board power source for controlling the power electronics module and control the power electronics module to operate in a manner causing the DC-link capacitor to be discharged.
