Abstract
An HID stabilizer power supply feedback circuit is composed of a resistor, a diode, a power supply positive wire, a power supply negative wire, a transformer and a controlling module. The HID stabilizer power feedback circuit is characterized in that after the resistor and the diode are connected in series, the resistor and the diode are connected at two ends of a circuit board of the power supply positive wire and the power supply negative wire in parallel. One line of a direct-current power supply of a 12V storage battery reaches the transformer, the other line of the direct-current power supply of the 12V storage battery reaches the controlling module, the controlling module starts a moss tube to work, secondary coils of the transformer output voltage, and the stabilizer works. Meanwhile, the current of the 12V direct current is current-limited by the resistor through the power supply positive wire and flows to the power supply negative wire from the diode, when a computer board detects that a current loop exists at a negative pole, a suspect fault of the computer board can be eliminated.
Description
Technical field
The utility model relates to a kind of motor vehicle illumination with the electric power loop device of HID stabilizer, is a kind of HID stabilizer power supply feedback circuit concretely.
Background technology
At present, a lot of automobiles equate detection headlight power during whether with standard configuration, or fracture of wire or power are unusual to detect bulb by the loop of tungsten lamp, and the trouble light of detection failure by panel board displayed.The operation principle of HID stabilizer and tungsten lamp are different fully, cause having the vehicle of this function, the trouble light Chang Liang of its panel board.The client needs to carry out the supporting of a decoder again to stabilizer, with the coupling that reaches power or the feedback of power supply, has increased fund and has brought loaded down with trivial details again to maintenance.
Summary of the invention
The purpose of this utility model is to provide a kind of HID stabilizer power supply feedback circuit, has realized that feedback signal is to eliminate the function that computer is suspected to be fault.
The utility model is realized with following technical scheme: this a kind of HID stabilizer power supply feedback circuit, its structure is made up of resistance, diode, positive source line, power-polar curve, transformer, control module.It is characterized in that resistance is connected in parallel on the wiring board two ends of positive source line and power-polar curve with after diode is connected in series.
The DC power supply one tunnel of 12V storage battery arrives transformer, and another road arrives control module, and control module starts MOSFET work, transformer secondary output output voltage, stabilizer work.Simultaneously, 12V direct current electric current after the resistance current limliting, moves towards anode power cord by diode from the cathode power supply line, after the computer plate detects negative pole current circuit is arranged, can eliminate the fault that is suspected to be of computer plate.
Electric current when described diode prevents also simultaneously that the positive and negative power supply line is anti-inserted falls away effect.
Described diode is with after resistance is connected, and it is under the normal voltage of 12V, and its wasted work rate is 20 milliamperes.
The operating current of described stabilizer is 4.2A, and just the bulb with the 50W ~ 60W of former car is complementary, and lights because of the not enough trouble light that causes of coupling of power and computer plate to reach elimination.
Beneficial effect is: improve stabilizer power with the detection of balance computer plate, and realized that feedback signal is to eliminate the function that computer is suspected to be fault.
