Implement controlled voltage source
Simscape / Electrical / Specialized Power Systems / Fundamental Blocks / Electrical Sources
The Controlled Voltage Source block converts the 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 starting as a sinusoidal or DC waveform corresponding to the initial values.
The Simulink input signal must be a complex value (phasor) when you are using the Controlled Voltage Source block in a phasor simulation, because in this case, Simscape™ Electrical™ Specialized Power Systems software does not automatically convert the input signal from time-domain into complex (phasor) signal.
Default is selected. If selected, initializes the Controlled Voltage Source block with the specified Initial voltage, Initial phase, and Initial frequency parameters.
The Source type parameter is not available if the Initialize parameter is not selected.
The 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.
This parameter is not available if the Initialize parameter is cleared. The initial voltage for the initialization of the source, in volts (V). Default is
The initial phase for the initialization of the source, in degrees. Default is
0. The Initial phase parameter is not available if the Source type parameter is set to DC.
The initial frequency for the initialization of the source, in hertz (Hz). Default is
0. The Initial frequency parameter is not available in the dialog box if the Source type parameter is set to DC.
Voltage to measure the voltage across the terminals of the Controlled Voltage Source block.
Place a Multimeter block in your model to display the selected measurements during the simulation. In the Available Measurements list box of the Multimeter block, the measurement is identified by a label followed by the block name:
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.
