There is provided an electronic device that includes a heatsink, a first dual IGBT coupled to the heatsink and configured to provide electrical power to a field exciter, a second dual IGBT coupled to the heatsink and configured to provide electrical power to a battery, and a third dual IGBT coupled to the heatsink and common to the field exciter and the battery charger. The exemplary electronic device also includes a single temperature sensor disposed in the heatsink, a controller configured to receive a temperature reading from the single temperature sensor and, based on the temperature reading, estimate a junction temperature of at least one of the first, second, or third dual IGBT. |
