Im trying to generate pwm pulses for single phase inverter using tms320f28335 dsp processor using matlab simulink 2022a can anyone help me with this issue.

the switching frequency is 50khz for the inverter. as im new to this can somone guide me from basics. i have installed all the support packages that is necessary for the code generation using matlab simulink.

Hello Deepak,

Refer to the following steps on generating PWM (Pulse Width Modulation) pulses for a single-phase inverter using the TMS320F28335 DSP processor with MATLAB:

Step 1: Setup Simulink Model

Open MATLAB and start a new Simulink model.

Add PWM Block: From the Library Browser, navigate to Texas Instruments C2000 library, and add a PWM block.

Step 2: Configure PWM for 50kHz

Double-click on the PWM block to open settings.

Set Switching frequency to 50 kHz.

Configure other parameters like Carrier signal and Dead time as needed.

Step 3: Generate Reference Signal

Use a Sine Wave block for generating a reference signal.

Connect it to the PWM block.

Step 4: Code Generation

Go to Model Configuration Parameters > Code Generation and select Texas Instruments C2000 as the target.

Build Model: Generate code by clicking Build Model.

Step 5: Load and Run on DSP

Use Code Composer Studio to load the generated code onto the TMS320F28335.

Connect the DSP to your inverter circuit to see PWM signals.

This approach should help you generate PWM pulses for your single-phase inverter using the TMS320F28335 DSP processor with MATLAB Simulink.

I hope this helps.
