Step Current

Step current source

Modelica Standard Library

	Description
	The Step Current source generates a step current with zero rise time.

	Equations
	$i = i_{p} = - i_{n} = I_{0} + I_{h} {\begin{array}{c} 0 & t < T_{0} \\ 1 & otherwise \end{array}$ $v = v_{p} - v_{n}$

Variables

Name	Units	Description	Modelica ID
$v$	$V$	Voltage drop between the two pins	v
$v_{x}$	$V$	Voltage at pin $x$ , $x \in \{n, p\}$	x.v
$i$	$A$	Current flowing from pin $p$ to pin $n$	i
$i_{x}$	$A$	Current into pin $x$ , $x \in \{n, p\}$	x.i

Connections

Name	Description	Modelica ID
$p$	Positive pin	p
$n$	Negative pin	n

Parameters

Name	Default	Units	Description	Modelica ID
$T_{0}$	$0$	$s$	Time offset (start time)	startTime
$I_{h}$	$1$	$A$	Height of the step	I
$I_{0}$	$0$	$A$	Current offset	offset
