Abstract
An inverter circuit for a brushless motor utilizes an IPM integrated circuit module. The module includes insulated gate bipolar transistors and has outputs for providing driving signals to the brushless motor based on control signals received at inputs from a microcontroller. A sensing circuit measures the current at the lines from the outputs of the IPM integrated circuit module to the motor. A feedback circuit processes the current measurements and provides signals corresponding to the measured current to the microcontroller.
