Description

The AC Current Source block implements an ideal AC current source. The positive current direction is indicated by the arrow in the block icon. The generated current is described by the following relationship:

I=Amplitude x sin(2pi x Frequency x t + Phase x pi/180)

Negative values are allowed for amplitude and phase. Negative frequency is not allowed, otherwise Simulink signals an error, and the block will display a question mark in the block icon. You can modify the three source parameters at any time during the simulation.

Example

Parallel connection of two Current Source blocks is used to sum two sinusoidal currents in a resistor.
