Voltage stabilization power supply overload indication ripple and peak inhibition circuit

Abstract

The invention discloses a voltage stabilization power supply overload indication ripple and peak inhibition circuit. The voltage stabilization power supply overload indication ripple and peak inhibition circuit comprises a constant current source circuit, an operational amplifier P1, a three-terminal voltage stabilizer U, a triode VT1, a triode VT2, a triode VT3, an indication lamp BL, an inductorL, a capacitor C1, a capacitor C2, a capacitor C3, a capacitor C4, a capacitor C5, a resistor R1, a resistor R2, a resistor R3, a resistor R4, a resistor R5, a resistor R6, a resistor R7, a resistorR8, a resistor R9, a diode D1 and a voltage stabilization diode D2. The voltage stabilization power supply overload indication ripple and peak inhibition circuit is reasonable in design, cannot only satisfy usage requirements of a power supply circuit, but also can display through an indication lamp when an electric load is overload, can prompt a user at first time about the overload condition ofthe electric load, can spare the user from labor of investigating abnormal conditions causing the electric load to shut down, can provide great convenience to the user and is applicable to popularization and usage.

Description

technical field [0001] The invention relates to a power supply circuit, in particular to an overload indication ripple peak suppression circuit for a stabilized power supply. Background technique [0002] The power supply circuit is used to connect the power supply and the electric load, so as to supply the power to the load. When the load is overloaded, the power circuit will be disconnected to prevent damage to the electronic components and electrical loads of the power circuit. After the power circuit is disconnected, the power supply cannot supply power to the load, and the load will stop working. Since the load stops working due to abnormality, it is necessary to check the cause of the abnormality. It is difficult to find the circuit disconnection of the power supply circuit due to the overload of the power load at the first time during use, which brings great difficulties to the investigation of abnormal load shutdown.

After the power circuit is disconnected, the power supply cannot supply power to the load, and the load will stop working

Since the load stops working due to abnormality, it is necessary to check the cause of the abnormality. It is difficult to find the power circuit disconnected due to the overload of the power load at the first time when using it, which brings great difficulties to the investigation of abnormal load shutdown.
