VERTICAL DEFLECTION CIRCUIT

摘要

A saw-tooth wave signal is fed to a non-inverted input terminal of a first power amplifier that constitutes a first negative feedback amplifier. A deflection coil (13) is connected at its one end to the output terminal of the first power amplifier, and a signal output from the other end of the deflection coil is fed to an inverted input terminal of the first power amplifier. The deflection coil is connected at the latter and via a resistor to the output terminal of a second power amplifier that constitutes a second negative feedback amplifier. The output terminal of the second power amplifier is connected to its inverted input terminal. When no signal is input, the DC voltage at the output terminal of the second power amplifier is equal to that of the first negative feedback amplifier. A circuit is provided between the non-inverted input terminal of the second power amplifier and the non-inverted input terminal of the first power amplifier in order to operate the second power amplifier whose input signal has a polarity opposite to that of the first power amplifier. @(17pp Dwg.No.1/4)@.
