Description

The DC Current Source unit is a DC source whose output current value is independent of the voltage at its terminals.

To avoid problems in numerical modelling, the block uses a small internal conductance. The conductor connects the + and - terminals of the unit and has a conductivity of GMIN:

By default, the value of GMIN is 1e-12 1/ohm.

Ports

Conserving

# + — positive terminal
scalar

Details

An electrical port connected to the positive terminal of a DC source.

Program usage name

p

# - — negative terminal
scalar

Details

An electrical port connected to the negative terminal of a DC source.

Program usage name

n

Parameters

# Constant value, DC — constant output current
A | pA | nA | uA | mA | kA | MA

Details

DC output current value, in A.

Units	`A` \| `pA` \| `nA` \| `uA` \| `mA` \| `kA` \| `MA`
Default value	`0.0 A`
