Abstract
The invention provides an automobile alternating-current generator. The automobile alternating-current generator comprises a three-phase alternating-current generator, a rectifier, a shunt, and a power generation detection end of the generator, wherein electric energy transmitted by the generator passes through two output ends of the shunt and respectively supplies power to a standby storage battery, a storage battery and electric equipment of an automobile; and a power generation signal can be output from the power generation detection end of the generator.
Description
One. affiliated technical field
The present invention relates to a kind of be used for can be simultaneously respectively to the standby battery of automobile, at AC generator for vehicle with storage battery and power consumption equipment power supply; He also has the positive pole that can check rectifier whether the power-generation detection circuit that surpasses the voltage existence of setting is arranged.
Two. background technology
At present, known AC generator for vehicle structure is made up of threephase alternator, voltage regulator, rectifier; Wherein the stator winding of threephase alternator connects rectifier, through rectifier the alternating current of its generation is become direct current.But the positive pole of rectifier is defeated to have only one to go out end, and this just can only be unfavorable in automobile power supply system, being provided with standby battery jointly to power consumption equipment, the storage battery power supply of automobile.
Three. summary of the invention
The present invention provide a kind of can be simultaneously respectively to the standby battery of automobile, at AC generator for vehicle, with the convenient standby battery that in automobile power supply system, is provided with storage battery and power consumption equipment power supply.
The technical solution adopted for the present invention to solve the technical problems is: by threephase alternator, voltage regulator, rectifier, shunt formed automobile alternating current generator; The cathode output end of rectifier connects a shunt, and shunt is to be made up of two diodes, and the negative pole of two diodes connects the cathode output end of rectifier jointly, and the positive pole of two diodes connects standby battery respectively, with storage battery and power consumption equipment; AC generator for vehicle when generating can be simultaneously respectively to standby battery, with storage battery and power consumption equipment power supply, and standby battery and with storage battery not conducting mutually; The power-generation detection circuit of generator is made up of a voltage stabilizing didoe and a resistance, and when the cathode voltage of rectifier was higher than set point, voltage stabilizing didoe was breakdown, the generating test side output HIGH voltage of power-generation detection circuit.
Advantage of the present invention is:
1. AC generator for vehicle is not influencing in charge in batteries and the power supply of vehicle power consumption equipment; Again can in the power-supply system of automobile, standby battery being set easily; And standby battery charged, and standby battery needn't be to the power consumption equipment power supply of vehicle.
2. can confirm easily through the generating test side of power-generation detection circuit whether generator is in generating state, and can be used as the transducer of confirming engine running.
Four. description of drawings
