Controlled Voltage Source

Ideal voltage source driven by input signal

  • Controlled Voltage Source block

Simscape / Foundation Library / Electrical / Electrical Sources


The Controlled Voltage Source block represents an ideal voltage source that is powerful enough to maintain the specified voltage across its terminals regardless of the current flowing through the source.

The output voltage is V = Vs, where Vs is the numerical value presented at the physical signal port.
