ADAPTIVE JUNCTION TEMPERATURE CONTROL FOR ELECTRIC MOTOR

This abstract first appeared for US patent application 18494757 titled 'ADAPTIVE JUNCTION TEMPERATURE CONTROL FOR ELECTRIC MOTOR

Original Abstract Submitted

A motor control system including an inverter having a diode and a transistor for generating an alternating current in response to a pulse width modulated direct current having a fixed amplitude and a processor configured to adjust a zero vector of the pulse width modulated direct current in response to a diode temperature and a transistor temperature such that the diode temperature equals the transistor temperature.
