Embodiment 1

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] Such as Figure 1 ~ Figure 3 As shown, a kind of power supply voltage stabilizing compensator described in the present invention comprises:

[0026] Filter unit: filter out the clutter of the input power supply, and output the standard voltage signal;

[0027] Charging current limiting module: receive the standard voltage signal, perform current limiting processing, and provide charging power;

[0028] Supercapacitor bank: used to store the electric energy of the charging power supply; output the first voltage and the second compensation voltage;

[0029] Voltage stabilizing module: stabilize the first voltage and output the first compensation voltage.

[0030] A further solution is: a contactor J1 is connected between the output terminal of the charging current limiting module and the voltage stabilizing module, and the control branch of the contactor J1 is ...

Abstract

A power source voltage stabilization compensator comprises a filtering unit, a charging current limiting module, a super-capacitor set and a voltage stabilization module, wherein the filtering unit conducts clutter filtering on an input power source and outputs a standard voltage signal; the charging current limiting module receives the standard voltage signal, conducts current limiting processingand provides a charging power source; the super-capacitor set is used for storing electric energy of the charging power source and outputs first voltage and second compensation voltage; and the voltage stabilization module conducts voltage stabilization on the first voltage and outputs first compensation voltage. When start of a vehicle engine or other reasons lead to instant drop of power supplyvoltage, the power source voltage stabilization compensator is used for providing power source compensation for equipment already in a working state and guarantees normal power supply of the workingequipment.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a power supply voltage stabilizing compensator. Background technique [0002] At the moment of starting the engine, everyone can clearly feel that the interior lights of the vehicle dim for a while, and then brighten again. This is due to the moment the car starts, the vehicle voltage is pulled down. The battery voltage drops at the moment of starting, and the voltage is pulled down, which will cause the internal lights and instrument backlights to dim for a short time, some solenoid valves cannot work normally, the ABS warning light falsely alarms, and the start-stop function is prohibited, etc. When the power supply voltage drops instantaneously due to reasons such as the start of the vehicle engine, it will affect the equipment that is already in operation. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a power supp...
