Title:
RECTIFIER
Document Type and Number:
Japanese Patent JPS56145778
Kind Code:
A
Abstract:
PURPOSE:To stabilize a rectifier by receiving the output of a rectifying circuit of diode bridge by differential amplifier operated by operational amplifiers, thereby reducing the number of the operational amplifiers. CONSTITUTION:A signal from a signal source S is rectified by a single-phase full- wave rectifying circuit made of diodes Dr1-Dr4 to produce its output between C and D. The output is applied to a differential amplifier including operational amplifier A to obtain a single-phase full-wave rectified output V0 from the input VS. Since the operational amplifier A is operated as a differential amplifier, both operational amplifier A and the signal souce S can employ common potential as a reference.
