Instead of using the SPWM block, I want to use the SVPWM (2-level) generator block. As is visible from below picture, I have used multiplex and Simulink-PS-converters.
Anyhow, this does not seem to work as the phase currents are not sinusoidal anymore, as one would expect.
Can anybody tell me what is the issue here and how it can be resolved?
Parameter settings:
Repeating sequence: Time values: [0 0.05/(1000*2*pi/60*4)] Output values: [0 2*pi]
SVPWM generator: Pattern #1, Switching frequency 10.000Hz
Simulation time changed to 0.05s
All other settings unchanged, compared to simscape example

Hi,
In your model I suspect the order of the PWM signals is not right.
I suggest using the PWM Generator (Three-phase, Two-level) block. This block will ask you for the switching frequency and sample time. You can check this example:
I hope this helps.
