High-voltage output stage integrated circuit

Abstract

The invention discloses a high-voltage output stage integrated circuit. The integrated circuit comprises a filter circuit and a modulation circuit; the filter circuit is connected with a RC (Resistance-capacitance) circuit in series, so as to filter out medium-high frequency clutters; the voltage is inputted into the modulation circuit after the voltage is stabilized and the proportion is amplified by an operational amplifier; the modulation circuit modulates the amplitude and outputs stable voltage by a thyristor and a three-end voltage-regulator tube; negative electrodes of the thyristor D4 and the thyristor D6 are divided into two paths to receive the voltage of the filter circuit; one path is connected with a capacitor C4 in series, so as to filter out the direct-current voltage in the alternating voltage by using the characteristic of circulating the alternating current and blocking the direct current of the capacitor C4; the other end of the capacitor C4 is connected with a negative electrode of the thyristor D5 and a control electrode of a three-end silicon controlled rectifier Q1; the thyristor D5 protects the circuit; if the potential of the control electrode of the three-end silicon controlled rectifier Q1 is too high, the three-end silicon controlled rectifier Q1 is reversely conducted to be connected with the ground; if the potential is too low, the three-end silicon controlled rectifier Q1 is not triggered to be conducted; in the same way, a same circuit is connected in parallel; the circuit consists of the thyristor D6 and a thyristor D7, a capacitor C5 and a three-end silicon controlled rectifier Q2. The integrated circuit effectively stabilizes the output voltage of the high-voltage integrated circuit, filters the frequency, and effectively regulates the abnormal voltage.
