There is provided an electronic device that includes a heatsink and a set of IGBTs coupled to the heafsiiik and configured to deliver power to a field exciter and a battery. The electronic device also includes a temperature sensor disposed in the heatsink and a controller. The controller is configured lo receive a temperature reading from the temperature sensor and, based on the temperature reading, determine a junction temperature for ai least one of the IGBTs of the set of IGBTs. The controller is also configured to de-rate an output power provided by each of the IGBTs based, at least in part, on the junction temperature. |
