## Description

The PCCVS (Polynomial Current-Controlled Voltage Source) block represents a voltage source whose output voltage value is a polynomial function of the current through 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:

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

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

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

where:

• Iin is the current through the input ports.

• p is the Polynomial coefficients parameter value.
