Time step and Plot step
Im working with a SPWM inverter.when I change time step,plot step accordingly to get correct waveform of the triangular signal,it will change some readings(THD). How do I verify these values ?

Hi there;
You must decrease your time step and plot step in case of studying the switched model. However, increasing the time step and plot step is extremely useful in case of using average model to speed up the simulation.
In fact, the PSCAD model is based on nonlinear differential equation, so increase the simulation step might shows unstable system operation
