Current Source AC

Purpose

Generate sinusoidal current

Library

Electrical / Sources

Description

pict

The AC Current Source generates a sinusoidal current between its two electrical terminals. The direction of a positive current is marked with an arrow. The momentary current i   is determined by the equation:

i = A ⋅sin(ω ⋅t+ φ)

where t   is the simulation time.


Note  A current source may not be open-circuited or connected in series to an inductor or any other current source.

Parameters

Each of the following parameters may either be a scalar or a vector corresponding to the implicit width of the component:

Amplitude
The amplitude A   of the current, in amperes (A). The default is 1.
Frequency
The angular frequency ω  , in s-1  . The default is 2*pi*50 which corresponds to 50 Hz.
Phase
The phase shift φ  , in radians. The default is 0.

Probe Signals

Source current
The source current in amperes (A).
Source voltage
The voltage measured across the source, in volts (V).
Source power
The instantaneous output power of the source, in watts (W).
