摘要： A system and method for monitoring the state of health of a power electronic system. Data representing an initial expected temperature of the circuit element and an initial value of an electrical parameter of the circuit element is obtained. An electrical pulse is applied to the circuit element to heat the circuit element. After the electrical pulse decays to a predetermined value, the electrical parameter of the circuit element is sensed and a subsequent value of the electrical parameter is obtained. A subsequent temperature of the circuit element is estimated based on the initial expected temperature of the circuit element, the initial and subsequent values of the electrical parameter, and the predetermined value of the electrical pulse. Based on the subsequent temperature, the signal that indicates whether the circuit element is operating as expected is generated.

摘要： A PWM strategy can be implemented to reduce device power losses and hotspot temperature in an inverter circuit that drives a synchronous motor. A method includes migrating a phase current from a power device with higher losses to a power device with lower losses. A PWM modulation signal can be modified to alter the inverter duty cycle and migrate phase current in the direction of lower losses. As an example, a PWM reference signal can be shifted to a lower value. A PWM loss reduction strategy can be performed while a motor is in a rotor-lock state to reduce device hotspot temperature. The PWM loss reduction strategy can also be performed when a motor is operating in a normal state, pushing PWM to DPWM, reducing switching and overall losses. The strategy can be practiced while a PMSM is operating as a motor, and can also be practiced during regenerative braking.
