Document Type and Number:
WIPO Patent Application WO/2021/166018
Kind Code:
A1
Abstract:
A noise suppression device (20) disposed between an AC power supply and a device to be controlled and transmitting a signal to the device to be controlled is provided with: a detection circuit (30) for detecting a specific signal; a waveform signal forming circuit (40) for forming a predetermined waveform signal from the specific signal detected by the detection circuit (30); a signal transmitter (50) for transmitting the waveform signal formed by the waveform signal forming circuit (40) to the device to be controlled; a state detector (60) for detecting a state signal indicating the state of the device to be controlled or the waveform signal forming circuit (40); and a gain adjuster (70) built in the waveform signal forming circuit (40) and adjusting the gain of the waveform signal in accordance with any one of the state signals detected by the state detector (60). The waveform signal adjusted by the gain adjuster (70) is transmitted to the device to be controlled.
