Dimmer with resistive load

Information

This model demonstrates the behaviour of a dimmer with phase-angle control with resistive load.

The reference voltage is prescribed by a trapezoid between zero and full voltage. The voltageToAngle block calculates the necessary phase angle, which is processed by the Signal2mPulse adaptor, applying the firing signals to the triac.

Dimmer with resistive-inductive load

Information

This model demonstrates the behaviour of a dimmer with phase-angle control with resistive-inductive load. Note that due to the inductance the current is not zero at the points in time wehre zero-crossing of the voltage occurs, and the triac stays conducting until the current becomes zero.

The reference voltage is prescribed by a trapezoid between zero and full voltage. The voltageToAngle block calculates the necessary phase angle, which is processed by the Signal2mPulse adaptor, applying the firing signals to the triac.

Soft start of an induction machine

Information

This model demonstrates a soft start of an induction machine: Voltage ramp is started at 0.1 s and should ramp up to nominal voltage within 4s, but current is limited to 2.5 times nominal current. At 5.5 s a voltage ramp down within 3 s is required.

Reference voltage is controlled by the softStartControl block, reference voltage is converted to firing angle by the voltageToAngle block. Firing angle is processed by the Signal2mPulse adaptor to firing signals which are applied to the triac.

Compare starting with firing angle by starting direct on line, star-delta starting, and starting via a transformer.
