S-za linearity correction circuit of horizontal deflection circuit

摘要

The S-shape linearity correction circuit of the disclosed horizontal deflection circuit is a S-shape of a horizontal deflection circuit that uses a plurality of field effect transistors (FETs) and a capacitor and a capacitor in combination with a push-pull circuit in parallel and in parallel with the linear correction coil. It relates to a linearity correction circuit.;The present invention is a horizontal oscillator for generating and outputting a horizontal oscillation frequency by the input horizontal synchronization signal, and a horizontal driver for generating and outputting an amplified pulse waveform of the same frequency as the horizontal oscillation frequency driven by the output signal of the horizontal oscillator; Connected to the horizontal deflection coil, a horizontal output part driven by an output signal of the horizontal drive part to supply current to the horizontal deflection coil, a horizontal deflection coil to generate a sawtooth current by receiving the output current of the horizontal output part, and a horizontal deflection coil And a control unit for applying a parabolic synchronization signal to the S-shaped correction unit.;Therefore, the present invention uses a push-pull circuit instead of a plurality of field effect transistors and capacitors and linearity correction coils to reduce the cost of using electronic devices, and to reduce the cost of the field effect transistors. The problem of component damage caused by this problem is reduced, the power consumption is reduced by using a combination of parallel and parallel capacitors, and precise S curve and linearity correction effects can be obtained through direct control by the controller.
