Greetings,
If you want to create a Triangular Wave Source in signal processing, you can use the following signal processing block: Triangular Wave Source. Additionally, if you set the duty cycle property of this component to 0 or 1, you can get a sawtooth waveform.
If you want to create these signals for PWM modulation for a specific converter block inside Typhoon, we highly recommend using the internal modulator for the specific converter you want to use - Control methods for Converters. This video covers all control techniques you can apply to the converters - Converter control.
Hope this helps,
