Voltage regulation system

The present invention provides a voltage adjustment system, and more particularly to a vehicle type voltage adjustment system.

The vehicles in the workshops all have voltage regulators to control the power consumption of the equipment in the vehicle, such as lights, direction lights, interior lights, warning lights, power consumption of the vehicle system, and the like. In general, there are two types of automotive voltage regulators, which are divided into short-circuit and switch-type.

The short-circuit system mainly has a rectifying circuit and a voltage stabilizing circuit. The rectifying circuit mainly converts the three-phase alternating current outputted by the magnet generator into three-way full-wave rectification to become a pulsating direct current. The voltage regulation loop mainly detects the voltage level of the pulsating direct current. When the voltage level of the pulsating direct current reaches the preset point, the voltage controlled rectifier (SCR) is triggered to short-circuit the three-phase electric current of the magnet generator through the controlled rectifier. To the ground, when the three-phase alternating current is turned from positive to negative, the controlled rectifier is turned off, so that the voltage can be stabilized at a certain voltage level, so that it can be used by various electrical equipment of the vehicle.

Wherein, the short-circuit voltage regulator is after the current generated by the magneto is deducted from the load output of the vehicle, and the excess electric energy is directly transmitted through the controlled rectifier. The short circuit to the negative terminal, so the short-circuit voltage regulator will cause waste of engine performance, and will continue to generate thermal energy. If the parts used in the vehicle are defective or the heat dissipation conditions are poor, it may cause the temperature of the internal parts of the vehicle to be too high and dangerous. On the other hand, although the switching voltage regulator has better engine performance than the short-circuit voltage regulator, the cost of the switching voltage regulator is too high, and the control loop is complicated. If the controlled rectifier is out of control, the high-voltage direct output of the magneto is caused. On the vehicle electrical equipment, there is a danger of burning electrical equipment.

An embodiment of the present invention provides a voltage adjustment system including a magnet generator, a switching module, and a voltage adjustment module. The magnet generator has a first output contact, a second output contact and a third output contact, the first output contact outputs a first power supply, the second output contact outputs a second power supply, and the third output contact outputs a third output power supply. The switching module is connected to the first output contact, the second output contact and the third output contact, and the switching module is electrically connected to the first output contact, the second output contact or the third output contact according to the switching instruction or Open circuit. The voltage adjustment module is connected to the switching module, and the switching module receives and corresponds to at least two of the first output contact, the second output contact and the third output contact according to the switching instruction. At least two of the first power source, the second power source and the third power source are rectified and regulated, and output output power, and the switching module is at least two of the first output contact, the second output contact and the third output contact When the circuit is disconnected, the voltage adjustment module stops receiving the first power source, the second power source, and the third power source.
