Motor Control Class: Lecture 8 - Power Stage Configuration (DevKit MotorGD)

Daniel_Popa — Mon, 19 Jun 2017 07:08:33 GMT

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;

Hi Daniel：

I can not open the attachment.

Beacause I use MATLAB R2015a, can you export previous version?

Thanks.

Hi rogerdai‌,

Sure, please find it attached in 2015a mdl format.

Hope you find it useful.

Best regards,
Daniel

Hi,

I'm trying to use this with the MOTORGD & REV E of the MPC5744P (MATLAB R2020b is what I'm running), and each time I try to run the coder I get an error claiming that it's trying to divide by 0 at some point. Could I have some assistance on this please?

Thanks,

Crispin
