d) Chattering-Off Sine

Overview
Sine wave which have a chattering pattern during the shut off state.
Application examples
•Simulates an AC power supply output waveform which follows the chattering pattern of a switch or
relay during output shut off.

Meaning of each parameter
The example shows the case where the amplitude range is ±FS.
•Shut off start phase (OffPhase)
The original sine wave begins to follow a chattering pattern
from this phase as it shuts off.
Variable range: 0.00
°
to 360.00
°
• Number of chattering instances (ChatterN)
The number of times it repeatedly turns off and on.
The repeated on and off portions have the same time
duration.
Variable range: 0 to 3
•Time On (Ton)
The amount of time one chatter is turned on.
Variable range: 0.00% to 20.00% of basic cycle
•Time Off (Toff)
The amount of time one chatter is turned off.
Variable range: 0.00% to 20.00% of basic cycle
The amplitude of the original Sine wave is fixed at ±FS. Please note that the amplitude may be less
than ± FS depending on each parameter setting.

Waveform examples
The polarity and amplitude range are all Normal, ±FS.
