The working principle of the MB90762HPMC-G-XXX-BNDE1 is based on three-phase PWM output. It is an IGBT drive with integrated three-phase current feedback for motor control. It has three output phases that represent the three phases of an AC motor, plus a fourth phase. The device has an on-chip gate drive, excitation control and current comparator, which are used to control the motor speed, torque and current.

When upstream PWM signals are provided, the on-chip transistor generates the required drive voltage to raise the gates of the IGBT. The X and Y signals from the current comparator are combined with the PWM signal to control the drive conduction angle, as shown in the following Figure2.

The input PWM voltage and current feedback are used to adjust the amplitude of the gate drive voltage for the IGBT in order to control the motor speed, torque and current. The motor speed is determined by the frequency of the input PWM signal. The current feedback is used to adjust the conduction angle of the IGBT, thus providing torque control. By adjusting the input PWM signal duty cycle, the applied voltage to the motor can be adjusted to obtain the desired motor speed and torque.
