In this 8th lecture of the motor control course we discuss about power stage (DevKit MotorGD) configuration that involves the configuration and initialization of the MC34GD3000 FET pre-driver via SPI commands and the setup of the FlexPWM peripheral to generate PWM commands to the inverter MOSFETs.
Main topics:
- What is MC34GD3000 FET pre-driver and how it works;
- FET pre-driver initialization sequece;
- Power Stage Configuration and Control pins;
- How to configure the FlexPWM to generate PWM commands and validate the hardware;
- How to configure the SPI communication;
Objectives:
- Understand MC34GD3000 role;
- Understand PWM;
- Understand SPI communication;
- Implement and validate models for power stage initialization, configuration and operation;
