• Description

The PVCVS (Polynomial Voltage-Controlled Voltage Source) block represents a voltage source whose output voltage value is a polynomial function of the voltage across the input ports. The following equations describe the voltage across the source as a function of time:

• If you specify an n-element vector of polynomial coefficients for the Polynomial coefficients parameter:

${V}_{out}=p\left(0\right)+p\left(1\right)*{V}_{in}+...+p\left(n-1\right)*{V}_{in}^{n-1}+p\left(n\right)*{V}_{in}^{n}$

• If you specify a scalar coefficient for the Polynomial coefficients parameter:

${V}_{out}=p*{V}_{in}$

where:

• Vin is the voltage across the input ports.

• p is the Polynomial coefficients parameter value.
