Abstract
The four-line self-excited single-function voltage regulator for automobile generator can regulate the magnetic field of rotor by changing the on-off state of exciting current flowing through rotor. When the voltage produced by the generator is below the regulated voltage, the regulator is disabled. When the output voltage of the generator exceeds the regulated voltage preset value, the excitation current is disconnected by the regulator. At this point the generator voltage drops, and when it drops to the lower voltage rating, the regulator reconnects the field current, the voltage again gradually rises, and the regulator begins a new regulation cycle. The four-wire self-excited single-function voltage regulator for automobile generator has the main regulation voltage range of 14 +/-0.25V for 12V system and 28 +/-0.3V for 24V system.
Description
Technical Field
The invention relates to an automobile voltage regulator, in particular to a novel self-excitation single-function automobile voltage regulator.
Background
The electric system on the automobile is mainly powered by the automobile generator, and the regulator is the core component for controlling whether the generator generates electricity or not, and is an indispensable important component of the automobile power generation system.
At present, the existing single-function series regulators need to provide larger exciting current through a rotor coil of a motor by an indicator lamp connected with a battery so as to generate a magnetic field, and a stator rotates to cut the magnetic field to generate current, so that a generator generates electricity. The functional terminals of the single-function series regulator are generally four terminals B +, D + and F, E or three terminals D + and F, E, the regulator mainly comprises a plurality of low-power switching tubes and a high-power switching tube, and the working voltage of the generator and the function of charging the storage battery are regulated through the switching tubes. According to the principle that the single-function series regulator can regulate the power generation of the generator only through exciting current, the single-function series regulator can be operated only by exciting the motor through larger exciting current which is provided by an indicator lamp connected with a storage battery.
With the development of the automobile industry and the LED industry and the national development requirements on the problems of energy conservation and emission reduction of automobiles, the application of the single-function series automobile regulator on the automobiles faces the following problems:
1) no electricity is generated at idle speed. Because the LED luminous tube on the instrument can only provide smaller exciting current for the motor, and the smaller magnetic field generated by the smaller exciting current can not enable the generator to rapidly generate electricity at a lower rotating speed, the requirement that the generator can also generate electricity at an idle speed of the automobile can not be met, namely the requirement of the current country on energy conservation and emission reduction of the automobile industry can not be met.
2) The adaptability is poor. When the same single-function regulator is used together with the indicator lamps on different automobile instrument panels, the generating rotating speed of the motor has great difference and can not be generally suitable for various automobile factories, thereby increasing the design cost of newly developed regulators.
3) Self-excitation is carried out to generate electricity. Along with the development of novel engineering automobiles, the engineering automobiles require that the generator can also work without connecting an indicator light and an ignition switch, but the single-function regulator which is commonly used at present and has low price does not have the function, and the generator can be used for generating electricity only by providing exciting current for the generator through an external indicator light or the ignition switch.
