Can I give Modulated Sine Wave as Input to CMPA of ePWM Block in MATLAB Simulink for SVPWM Generation ?

I am Working on 3 Phase Inverter.

So I am using TI Delfino F28379D LaunchPad.

So For 20 KHz Switching Frequency What will be Setting of ePWM Block ?

Hi @PANDIT DHANRAJ SURESH

I understand that you are working on a 3-phase inverter using the TI Delfino F28379D LaunchPad and are looking to configure the ePWM block in Simulink for SVPWM generation with a 20 kHz switching frequency.

You can follow the below steps to achieve this:

• You can use a modulated sine wave as an input to the CMPA register of the ePWM block for SVPWM generation.
• I recommend referring to the following documentation, which provides a step-by-step guide for setting up ePWM block parameters and generating PWM waveforms: https://www.mathworks.com/help/ti-c2000/ug/epwm-waveform-example.html
• This documentation will guide you in setting up the ePWM block effectively for your 20 kHz switching frequency.
