Current-controlled voltage source (SPICE H)#

The Current-controlled voltage source (SPICE H) block is a model of a voltage source that is functionally similar to the current-controlled voltage source (CCVS) of the standard SPICE libraries.

The block has infinite resistance at the input and zero resistance at the output. The block’s output voltage is numerically equal to:

when selecting the option LINEAR (1) :

(1)#\[U_{out}=K \cdot I_{in}\]

where:

\(K\) – gain coefficient;

\(I_{in}\) – instantaneous value of current at the input.

when selecting the option POLY (2) :

(2)#\[U_{out}=\Sigma^n_{i=1}K_i \cdot I_{in}^{i-1}\]

where:

\(n\) – order of the polynomial;

\(i\) – ordinal number of the polynomial coefficient;

\(K_i\) – value of the i-coefficient of the polynomial.
