A system for an electrified vehicle, such as a battery electric vehicle (BEV), includes an inverter and a controller. The inverter is configured to drive a traction motor with electrical power from a traction battery, such as a lithium ion phosphate (LFP) traction battery, according to a configuration of a power switch (e.g., IBGT or MOSFET) of the inverter. The system further includes a controller configured to control a variable gate driver resistance for the power switch in a closed loop fashion to achieve a target temperature of the inverter. The system may further include a heating coolant loop for transferring heat generated by the inverter to the traction battery to warm the traction battery. The controller may be further configured to further control a switching frequency of the power switch in the closed loop fashion to achieve the target temperature of the inverter.
