I used ee_power_factor_correction command in MATLAB. How do I find the THD for this model?

If you’re referring to total harmonic distortion, see the Simscape Electical function ee_calculateThdPercent.

If your model is in SIMULINK, use THD module from Simscape / Electrical / Specialized Power Systems / Sensors and Measurements block set.

@Dr Narayanaswamy P R Iyer I have used the THD module, and it works fine. However, the values are incorrect. For example, it should be below 5, but mine is above 10. Can you please tell me how to reduce that?

Check the result by setting sample time to zero and also by setting it to 50e-6 Second.
