AC Voltage Source (Power System Blockset)

Implement a sinusoidal voltage source

Library

Description

The AC Voltage Source block implements an ideal AC voltage source. The output and input of the block correspond respectively to the positive and negative terminals of the source. The generated voltage U is described by the following relationship:

U=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

Two Voltage Source blocks at different frequencies are connected in series across a resistor. The sum of the two voltages is read by a Voltage Measurement block.
