Small Signal Perturbation

This block is included only in the PLECS Standalone library.

Purpose

Generate perturbation signal for small-signal analysis

../../_images/smallsignalperturbation2.svg

During a small-signal analysis that references this block, it generates the appropriate perturbation signal: a sinusoidal signal for an AC Sweep and a discrete pulse for an Impulse Response Analysis. At all other times the perturbation is zero.

For detailed information regarding small-signal analysis see chapter Analysis Tools.

Parameters

Show feed-through input: When set to on, the block displays an input port. The output signal is the sum of the input signal and the perturbation. The default is off.
