Reply To: Maxwell circuit – PWM

[Tamami Yamanaka]

Hello,

I apologize for misunderstanding your question in my previous response. The VPWM source in Maxwell circuit provides a signal wave (sinusoidal), and does not output the Carrior (triangular) and PWM (pulse) signals. 

Instead of Maxwell circuit editor, Twin Builder (Simplorer) is the way to build a circuit that explicitly generates a PWM signal. For example, the basic elements have a Comparator that compares a control signal generated by Sine Wave or a carrier signal generated by Triangular Wave, and generates a high output when the control signal exceeds the carrier signal, and a low output otherwise.

If you need more specific information on generating and comparing waveforms, please refer to the help section of Twin Builder or contact Ansys support.
