Thyristor Pair

Purpose

Thyristor rectifier/inverter module

Library

Electrical / Power Modules

Description

This series connected thyristor pair is implemented with a single switch and controlled current and voltage sources. One thryistor at most may conduct at a given time. The DC side of the rectifier/inverter has current source behavior. The output terminal is typically connected to an inductor.

The single switch implementation has fewer conduction states compared to two Thyristor components. This reduces the number of switching combinations when generating code from a simulation model. See Code Generation for Physical Systems for details.

When generating code for the thyristor pair the internal switching element is modeled as either an ideal or non-ideal switch. See Ideal and Non-Ideal Switch Models in Electric Circuits for detailed descriptions of the switch model implementations.

Note

The thyristor pair cannot model a shoot-through, i.e. the situation where both thyristors conduct at the same time.

Parameters

Switch model (CPU code generation)

Select the switch model in the generated code.

Fundamental grid frequency (Hz)

Frequency where non-ideal switches in the open state have increased series impedance. The default is 0.
