The application discloses a closed-loop feedback voltage stabilizing circuit. The closed-loop feedback voltage stabilizing circuit includes: a voltage dividing circuit, which is used to divide the voltage at the input end of the voltage stabilizing block to obtain a divided voltage, and input the divided voltage to a comparison circuit; the comparison circuit is connected to the voltage dividing circuit for According to the comparison between the divided voltage and the preset voltage, the current flowing through the input terminal of the isolated linear optocoupler is adjusted based on the comparison result; the triode, the base of the triode is connected to the output terminal of the linear optocoupler, and is used to output the current according to the linear optocoupler Control the output current of the collector of the triode and the voltage between the poles and emitters to adjust the voltage at the input terminal of the voltage stabilizing block to stabilize it at the optimum voltage value. Through the present application, the problem of heavy rear-end load of the voltage stabilizing block and excessive front-end voltage ripple in the voltage closed-loop circuit in the related art is solved.
Description
technical field [0001] The present application relates to the field of voltage closed-loop circuits, in particular, to a closed-loop feedback voltage stabilizing circuit. Background technique [0002] At present, in the closed-loop circuit of the voltage at the input terminal of the voltage stabilizing block, the ripple of the voltage value at the input terminal will affect whether the power supply at the rear end of the voltage stabilizing block can output stably, thereby affecting the stability of the power supply system. Such as figure 1 As shown, when the load connected to the output terminal Uo of the voltage regulator block increases, the increase of the load current will lead to a corresponding increase in the front-end current of the voltage regulator block, and the voltage division of the resistor R will increase accordingly, and the input voltage Ui of the voltage regulator block will decrease. The greater the load fluctuation, the greater the Ui ripple will be. ...
