This library provides power converters for DC and AC single and multi phase electrical systems. The PowerConverters library contains three types of converters.

General types of AC/AC converters are currently not provided in this library.

Converter characteristics


General background knowledge on power converters and power electronics can be found in [Skvarenina01] and [Luo05]. A freely available book is available in [Williams2006].

AC/DC converters are also called rectifiers

Component classification

Conventional AC/DC converters contain diodes and thyristors. If thyristors are used, the output voltage of the rectifier can be controlled. If only diodes are used, the output voltages is solely dependent on the input voltage and the characteristic of applied diodes.

Topology classification

The PowerConverters library provides bridge and center tap rectifiers for single and multi phase supply, see AC/DC converters.


For each of the provided rectifiers a control model is available. These control models have electrical connectors to be connected with the AC supply. The firing angle of thyristor rectifiers can either be set by a parameter or a signal input.


A variety of examples is provided at Examples.ACDC. These examples include different kinds of DC loads. Even the control characteristics of the rectifiers can be obtained experimentally; the names of these models contain _Characteristic.

There are a single and multi phase DC/AC converter model provided by the PowerConverters library.


There are currently no space phasor pulse width modulation (PWM) models provided. However, for operating the single and multi phase inverter the PWM controller can be used.


Some examples are provided at Examples.DCAC.
