Title:
WAVEFORM SHAPING CIRCUIT
Document Type and Number:
Japanese Patent JP2000116133
Kind Code:
A
Abstract:
To provide a waveform shaping circuit for improving a current waveform of a power line.
A waveform shaping circuit 102 is provided with an input terminal 104, an output terminal 106, and an earth terminal 108. Between the input terminal and the earth terminal, a first circuit 110, 112 is inserted to transmit a divided line voltage signal to the output terminal. The divided line voltage signal is the line voltage divided by a first fixed factor when the line voltage is a threshold or below. A second circuit 114 inserted between the output terminal and the earth terminal deforms the line voltage signal when the line voltage is the threshold or above to flatten the peak of an output waveform.
