Embodiment 1

[0020] like figure 1 , the reference voltage nodes V1-V4 can be powered by a DC voltage source or a microcontroller voltage output terminal, the overshoot signal is introduced through the input voltage signal Vin, and the working state of the depletion type field effect transistor Q2 is a non-modulation state, That is, the input voltage signal is directly equal to the output voltage signal Vout; for the reference voltage node V2, it is necessary to keep the difference between the input voltage signal and the positive voltage of the reference voltage node V2 higher than the voltage value of the modulation drive signal; when the voltage value of the reference voltage node V3 is higher than Modulate the voltage value of the driving signal or when the comparator U6 outputs a high level, and when an overshoot signal is detected at the non-inverting input terminal of the operational amplifier U2, the NAND gate U3A makes the field effect transistor Q1 cut off, and the operational ampl...

Abstract

The invention discloses a voltage regulator for an intelligent controller and relates to the field of circuit designing. The voltage regulator aims at addressing the technical problems of output voltage overshoot or over-strong negative gain caused by unreasonable arrangement of overshoot inhibition circuit. According to the invention, the voltage regulator includes a linear compensation drive circuit which receives an input voltage signal; a first operation amplifier which is intended for intercepting the output voltage signal, receiving a feedback signal output by the linear compensation drive circuit and outputting a regulation drive signal to the linear compensation drive circuit; a voltage detection circuit which receives the regulation drive signal which is output by the first operation amplifier; an overshoot detection circuit which receives the feedback signal output by the linear compensation drive circuit and a detection signal output by the voltage detection circuit. According to the invention, the voltage regulator is intended for providing voltage regulation.

Description

technical field [0001] The invention relates to the field of circuit design, in particular to a voltage modulator used for an intelligent controller. Background technique [0002] In the existing technology, the automatic control part and the motor part use the same AC power supply, introduce more unstable loads and a large number of system electromagnetic noise and overshoot signals, etc. unconventional situations; therefore, the introduction of high-efficiency and reasonable voltage modulation device is very necessary. For a voltage modulator with overshoot suppression, such as a modulator with a Zener diode, since the output is limited by the non-differential chopping method, it suppresses the input signal gain and is not suitable for the feedback detection of the control chip; The modulator with the structure of operational amplifier and field effect tube, when the input signal is a negative signal source, there is unnecessary overshoot suppression, resulting in the out...
