Description

The motorcycle rectifying pressurizer

The utility model relates to a kind of rectifying pressurizer that is used for stablizing the motorcycle utilization voltage.

Existing motorcycle regulator rectifier circuit has two kinds, a kind of only is to charge in batteries, play the rectifying and voltage-stabilizing effect, its method for stabilizing voltage is: when the storage battery both end voltage raises, control by circuit, force the output current shunting and realize voltage stabilizing, load electricity consumption (as the car light electricity consumption) then is to draw centre tap by the stator winding of generator directly to adopt Alternating Current Power Supply; Another kind of circuit is that generator unit stator winding output AC is electric all by rectifying and voltage-stabilizing, and to the electric apparatus of whole vehicle power supply, simultaneously also to charge in batteries, this circuit principle of stabilized voltage is identical with preceding a kind of circuit principle of stabilized voltage again, all is to adopt the shunting voltage stabilizing.Above-mentioned shunting voltage stabilizing, energy consumption is big, and the electronic component heating is serious, causes the component ageing degree obviously to be accelerated, and the circuit complexity.

Goal of the invention of the present utility model is to provide that a kind of less energy consumption, circuit are simple, the motorcycle stabilized rectifier of electronic component long service life.

The utility model mainly is made of rectification circuit, controllable silicon BG, voltage comparator T, the positive pole of the positive pole of rectification circuit and voltage comparator T joins, the trigger electrode of the output of voltage comparator T and controllable silicon BG joins, the plus earth of voltage comparator T negative pole, controllable silicon BG, the negative electrode of controllable silicon BG and the negative pole of rectification circuit join.During use, the input of rectifying pressurizer and the output of motor generator join, the output of rectifying pressurizer and storage battery E and join with electric loading R, like this, the alternating potential that produces on the generator is by the rectification circuit rectification, charge for load R electricity consumption and storage battery E after the controllable silicon BG pressure regulation, the effect of voltage comparator is when storage battery E both end voltage is lower than set point, comparison by voltage comparator T, output triggering signal control controllable silicon BG conducting, to improve the voltage at storage battery E two ends, when storage battery E both end voltage was elevated to set point, voltage comparator T was by comparing, and voltage comparator T stops to export triggering signal, controllable silicon BG is ended, generator no longer to storage battery E with electric loading R power supply, impels storage battery E both end voltage to reduce, thereby realizes the purpose of rectifying and voltage-stabilizing.

The utility model compared with the prior art, it is big to have overcome the existing energy consumption of existing shunting voltage stabilizing, the electronic component heating is serious, make the aging shortcoming of accelerating of electronic component, saved the energy, prolonged the useful life of electronic component, the utility model also has simple, the advantage of low manufacturing cost of circuit structure in addition.

Fig. 1 is the utility model voltage stabilizing rectification circuit schematic diagram.

Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:

As shown in the figure, the utility model is mainly by being made of rectification circuit D, controllable silicon BG, voltage comparator T, the positive pole of the positive pole of rectification circuit and voltage comparator T joins, the trigger electrode of the output of voltage comparator T and controllable silicon BG joins, the plus earth of voltage comparator T negative pole, controllable silicon BG, the negative electrode of controllable silicon BG and the negative pole of rectification circuit join.During use, the output of the input of rectifying pressurizer and motor generator L joins, the output of rectifying pressurizer and storage battery E and join with electric loading R.

Above-mentioned rectification circuit can be selected bridge rectifier 8A/600V for use, controllable silicon BG can select BT151-600R for use, like this, and when the magneto rotating speed changes between 2000r/min-10000r/min, output voltage only fluctuates between 13.8V-14.25V, and voltage fluctuation also seldom during transformation load.
