Information

The following AC/AC converter topologies are currently included in the PowerConverters library.

• Single-phase dimmer with triac
• Polyphase induction machine soft starter with triac

Control

To apply firing signals to the triac, the SignalPWM model is provided.

The Voltage2Angle block calculates phase angle from reference voltage.

To control the soft start of an induction machine, the SoftStartControl block is provided. It applies a voltage ramp during start, setting the ramp on hold whenever the measured current exceeds the maximum current. Furthermore, a ramp down can be applied for stopping the drive.

Examples
