Ideal sinusoidal current source
Electrical Sources
The AC Current Source block represents an ideal current source that maintains sinusoidal current through it, independent of the voltage across its terminals.
The output current is defined by the following equation:
$$I={I}_{0}\cdot \mathrm{sin}(2\pi \cdot f\cdot t+\phi )$$
where
I | Current |
I_{0} | Peak amplitude |
f | Frequency |
φ | Phase shift |
t | Time |
The positive direction of the current flow is indicated by the arrow.
Note:
For Release 2012b and earlier, the unit definition for Hz was |
Peak current amplitude. The default value is 1
A.
Phase shift in angular units. The default value is 0
.
Current frequency, specified in Hz or units directly convertible
to Hz (where Hz is defined as 1/s
). For example, kHz
and MHz
are
valid units, but rad/s
is not. The default value
is 60
Hz.
The block has two electrical conserving ports associated with its terminals.
