THERMAL SENSING AND CONTROL OF A TRANSISTOR BOARD

An electric motor circuit includes a motor controller having a plurality of gate drivers and an inverter configured to receive direct current (DC) power from a source and output alternating current (AC) power to an electric motor. The inverter includes a plurality of transistor elements. Each transistor element includes multiple transistors arranged on a transistor board. Multiple temperature sensors are configured to monitor a plurality of temperatures on each transistor element. The motor controller is configured to alter a pulse width modulation (PWM) control of a first subset of transistors on a first transistor element in response to a first subset of temperature sensors detecting a temperature exceeding a threshold temperature and a second subset of temperature sensors not detecting a temperature exceeding the threshold.
