What is current controlled voltage source?
Current Controlled Voltage Source (CCVS) A CCVS is a voltage source where the voltage is controlled by a current elsewhere in a circuit. Here, we’ve specified a gain of 100, and a controlling current of R1.nA, meaning the current into terminal nA of resistor R1: Current Controlled Voltage Source (CCVS) Example.
What is the purpose of controlled voltage source?
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.
How is a current controlled voltage source different from resistance?
The dependent sources show interdependence of different branches. i.e current through one branch controls voltage through some other branch or current through one branch controls current through some other branch. So, dependent sources can be generalized as the concept of resistance but they are not same as resistance.
What’s the difference between a CCVS and a resistor?
\\$\\begingroup\\$. A current controlled voltage source produces a voltage that is linearly proportional to a current. A resistor has the same behavior. And the gain for a CCVS is measured in ohms, which is the same unit that measures a resistor.
How does a voltage controlled resistor work in spice?
Voltage-Controlled Resistor. To sense current, SPICE uses a voltage source VSENSE (0V). It’s set to 0V so there’s no effect on the output voltage. The other source, ERES, generates the voltage across the “resistor” based on the sensed current times your desired resistance VALUE={I(VSENSE)*10K}.
How is the voltage of a resistor determined?
The other source, ERES, generates the voltage across the “resistor” based on the sensed current times your desired resistance VALUE= {I (VSENSE)*10K}. A simple addition to the above resistor model gives you a voltage-controlled resistor.
