PWM Modulator
Description
Universal PWM Modulator for 3-phase 2-level VSIs. Generates six gate signals according to the selected modulation strategy (SPWM, SVM, DPWM-x, THIPWM…).
Behaviour is implemented in the C++ solver model. This C# class provides the schematic symbol, pins, parameters and scopes for the SIMBA GUI.

Parameters
| Name | Description |
|---|---|
| SwitchingFrequency | Switching frequency [Hz] |
| PWMType | PWM modulation type (cast to enum in solver) |
| SamplingTime | -none or 0: No sampling. The system will be solved in the Newton loop (default). -auto: Inherit the sampling time of its source device. -Sampling Period: defined in seconds. |
