Diode Pair

Purpose

Diode rectifier module

Library

Electrical / Power Modules

Description

This series connected diode pair is implemented with a single switch and controlled current and voltage sources. One diode at most may conduct at a given time. The DC side of the rectifier has current source behavior and the voltage across the series connected diodes (anode to cathode) must always be negatively biased. The AC side is typically connected to an inductor.

The single switch implementation has fewer conduction states compared to two Diode 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 diode rectifier 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 diode pair cannot model a shoot-through, i.e. the situation where both diodes conduct at the same time. Since the DC side is not clamped, the anode to cathode voltage always be negative.

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.
