This component models one of the following power electronic devices:
All devices are represented as a two-state resistive switch with an optional RC snubber connected in parallel with the device, as shown below:
The Thyristor, GTO and IGBT models require an input gating pulse and can be applied to high frequency switching and pulse width modulation power electronic circuits. Interpolated firing pulses can be supplied to these devices by using the Interpolated Firing Pulses component. In simulations such as Voltage Source Converters or other FACTS devices, care must be taken in ensuring the observed losses are realistic.
The Interpolation Algorithm is automatically invoked during all naturally commutated turn ON and turn OFF events (including forward break-over) in order to calculate the exact instant of switching. Please note however, that device turn ON or OFF using a gate signal is not interpolated unless specifically selected in the input parameters.
