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:

  $$V_{out}=p(0)+p(1)*V_{in}+\mathrm{...}+p(n-1)*V_{in}^{n-1}+p(n)*V_{in}^n$$

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

  $$V_{out}=p*V_{in}$$

where:

• V_in is the voltage across the input ports.

• p is the Polynomial coefficients parameter value.
