Voltage stabilizing circuit used for power generator

Abstract

The invention relates to a voltage stabilizing circuit used for a power generator. An output terminal of the power generator is connected with a first electric appliance and a storage battery, the voltage stabilizing circuit comprises a normally-open load quick-break relay and a controller, the load quick-break relay is provided with a first anode main contact, a first anode auxiliary contact, a first cathode main contact and a first cathode auxiliary contact, a contactor is connected between an anode of the storage battery and the output terminal of the power generator, two terminals of a contactor coil are the second anode auxiliary contact and the second cathode auxiliary contact respectively, both the first anode main contact and the first anode auxiliary contact are connected with the anode of the storage battery, the first cathode auxiliary contact is connected into the controller, the first cathode main contact is connected into the second anode auxiliary contact of the contactor, the second cathode auxiliary contact is grounded, and a neutral terminal of the power generator is connected into the controller. By the voltage stabilizing circuit, current generated by the power generator can be adjusted in realtime, transient high-voltage current generated when a system works and surge generated when the system stops can be consumed, so that reliability of the whole electrical system is improved.

Description

Technical field [0001] The present invention relates to the field of vehicle electrical technology, in particular to a voltage stabilizing circuit for generators, which can be widely used in the fields of automobiles, engineering machinery and the like. Background technique [0002] The speed of the generator changes with the engine speed. When the generator is working, it simultaneously charges the battery and provides energy to the entire electrical system. Although the alternator has a built-in regulator. However, the regulator uses the synergy of resistors, Zener diodes, and triodes to achieve voltage stabilization, which has a certain hysteresis, and the use of the above-mentioned analog electrical components to achieve voltage stabilization is relatively extensive and the voltage stabilization is not accurate enough. It is inevitable that it will have an impact on the electrical system of the whole machine, especially the knees of the controller. Over time, the electrica...

Problems solved by technology

Over time, the electrical and control system of the whole machine may have inexplicable intermittent problems, and it is difficult to troubleshoot

[0003] In addition, there is a DC-DC converter on the market that can convert "coarse electricity" to "fine electricity", but this kind of converter is expensive, and is limited by price and power, and is generally only suitable for a part of the entire vehicle. The electricity is converted from "coarse electricity" to "fine electricity"
