Electric circuit based on dependent source with Simulink

Create an electric circuit with a dependent source using MATLAB Simulink

Step-by-Step Instructions1. Add Voltage Source (Control Signal)

• Use an AC Voltage Source or Step Voltage Source.
• Connect to a Resistor for loading (optional).
• Tap the voltage using a Voltage Measurement block.

2. Add Controlled Voltage Source

• Place the Controlled Voltage Source block.
• Its input port (Simulink signal) takes the measured voltage (or a scaled version).
• You can use a Gain block from Simulink if you want Vout=k⋅VcontrolV_{\text{out}} = k \cdot V_{\text{control}}Vout​=k⋅Vcontrol​.

3. Connect the Output Circuit

• Add a Resistive Load at the output of the Controlled Voltage Source.
• Connect everything to Ground.

4. Monitoring

• Use another Voltage Measurement block on the output.
• Feed this to a Scope.

5. Simulation Settings

• Use the Powergui block (from SimPowerSystems > Extras).
• Choose “Continuous” or “Discrete” solver in Powergui settings.
