Abstract
An electrolytic capacitor reformation system for a vehicle includes an electrolytic capacitor, a motor driver module, a switching device, a resistor, and a switching control module. The electrolytic capacitor receives power from a battery of the vehicle. The motor driver module receives power from the electrolytic capacitor and drives an electric motor of the vehicle. The switching device and the resistor are connected in series in a current path between the battery and the electrolytic capacitor. The resistor limits current flow through the current path. The switching control module selectively transitions the switching device to a closed state to reform the electrolytic capacitor.
