Description

The Controlled Voltage Source block converts a Simulink^® input signal into an equivalent voltage source. The generated voltage is driven by the input signal of the block.

You can initialize the Controlled Voltage Source block with a specific AC or DC voltage. If you want to start the simulation in steady state, the Simulink input must be connected to a signal that begins the simulation as a sinusoidal or DC waveform that corresponds to the initial values.

Note

The Simulink input signal must be a complex value (phasor) when you use the Controlled Voltage Source block in a phasor simulation, because the Simscape™ Electrical™ Specialized Power Systems software does not automatically convert input signals from time-domain signals to complex (phasor) signals.

Ports

Input

s — Control signal

physical signal

Simulink physical signal input port associated with the control signal.

Conserving

+ — Positive terminal

specialized electrical

Specialized electrical conserving port associated with the positive terminal of the voltage source.

- — Negative terminal

specialized electrical

Specialized electrical conserving port associated with the negative terminal of the voltage source.

Parameters

Initialize — Enable source initialization

on (default) | off

Initializes the Controlled Voltage Source block with the specified values of the Initial amplitude (V), Initial phase (deg), and Initial frequency (Hz) parameters.

Source type — AC or DC voltage source

AC (default) | DC

Type of voltage source. Select AC (default) to initialize the Controlled Voltage Source block with an AC voltage source. Select DC to initialize the Controlled Voltage Source block with a DC voltage.

Dependencies

To enable this parameter, select Initialize.

Initial amplitude (V) — Amplitude at simulation start

0 (default) | scalar

Initial amplitude of the source, in volts (V).

Dependencies

To enable this parameter, select Initialize.

Initial phase (deg) — Phase at simulation start

0 (default) | scalar

Initial phase of the source, in degrees.

Dependencies

To enable this parameter, select Initialize and set Source type to AC.

Initial frequency (Hz) — Frequency at simulation start

0 (default) | nonnegative scalar

Initial frequency of the source, in hertz (Hz).

Dependencies

To enable this parameter, select Initialize and set Source type to AC.

Measurements — Source measurements

None (default) | Voltage

Select Voltage to measure the voltage across the terminals of the Controlled Voltage Source block.

To measure and voltage, place a Multimeter block in your model to display the selected measurements during the simulation. In the Available Measurements pane of the Multimeter block, the measurement is identified by a label followed by the block name:

Examples

The power_controlvolt example uses Controlled Voltage Source blocks to generate a 60 Hz sinusoidal voltage containing a third harmonic. One Controlled Voltage Source block is initialized as a 120 V AC voltage source with an initial frequency of 60 Hz and initial phase set to 0. The second Controlled Voltage Source block is not initialized.
