Ideal sinusoidal current source
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:
The positive direction of the current flow is indicated by the arrow.
Note: For Release 2012b and earlier, the unit definition for Hz was rev/s, whereas in R2013a it was changed to be 1/s, in compliance with the SI unit system. For this block it means that you must specify frequency in units of Hz or directly convertible to Hz, such as 1/s, kHz, MHz and GHz. In 2012b and earlier you could also specify frequency in angular units (such as rad/s or rpm), but this is no longer possible because the internal equation of the block now uses the 2π conversion factor to account for the 1/s unit definition. If you use this block in a model created prior to R2013a, update it by using the slupdate utility. For more information, see the R2013a Release Notes.
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.
