Through the inverter, the incoming DC voltage regulator can be used to raise the voltage to the voltage required by the charger with an electronic transformer, and after rectification, an electronic voltage regulator can be connected. But it stands to reason that when you buy this fan, you should come with a set of electronic charging equipment, and it is a wide voltage charging, that is, the input voltage fluctuation range is very large. You can enter the circuit diagram of an electronic booster or converter or inverter or voltage regulator in the web page, and there are many of them, you can take a look.

The original generator was an alternating current that was rectified by a bridge and then output direct current. You can make a voltage doubling rectifier and switch to the voltage doubling rectifier output when the output is low, and the output voltage can be increased by more than 70. The circuit is very simple, diodes and electrolytic capacitors are just known, electrical repairers, middle school physics teachers.

The AC point can theoretically be boosted by the coil, that is, when the output power is constant, the current is proportional to the voltage, and the voltage after the increase is adjusted through a sliding coil to reach the charging voltage of the battery. However, a voltmeter should be installed at the output end of the transformer for easy observation. In addition, due to the unstable output power of wind turbines, the sliding blades may also have to be constantly adjusted.
In addition, the output power of the wind turbine is unstable, and then under the condition of ensuring the stability of the charging voltage, the charging current will definitely be strong and weak. Note that when the current is too strong, it is not good for the battery!!

1. Transformer transformer.
The main function of the transformer is to convert the voltage and transmit electric energy, which can increase the voltage or decrease the voltage; According to different voltages and powers, transformers with different ratios and turns are wound. The output power can be very large, and it is often used to step down and boost in the power supply of the larger power car, which can isolate the primary power supply from the secondary load, which is beneficial to safety.
2. Resistance step-down.
This is a very common step-down method used in electronic circuits, which realizes voltage division and current limiting through series resistance; Shunt action is realized by parallel resistors; The voltage can be easily adjusted through the variable resistor, and the voltage can be regulated by both AC and DC; The disadvantage is that the resistor is an energy-dissipating component, which will generate disadvantages, and the resistor with larger power is large.
3. Capacitor step-down.
The capacitor step-down function is innate, but now the manufacturing technology has developed by leaps and bounds, and the voltage resistance and capacity of the capacitor have been improved, the volume has been reduced, and the cost has been reduced, so it has been widely used. Through the current of the capacitor i=U XL, and the capacitive reactance xc=1 2 fc, it can be seen that the larger the capacitance of the capacitor, the smaller the capacitive reactance, and when the load such as resistance is connected in series with it, the capacitor plays the role of voltage divider.
4. Inductance step-down.
Inductor buck was applied relatively early, and the ballast on the fluorescent lamp we used was a typical buck inductor. In the electric fan, the governor is made of inductor taps; Its step-down principle is the same as that of the capacitor, and its inductive reactance XL=2 F, and there will be impedance and voltage drop when the alternating current passes; The filter inductor in the rectifier circuit actually acts as a step-down, reducing the AC component.
5. Thyristor voltage regulation.
This voltage regulation method can realize stepless voltage regulation and closed panicle hunger, and is widely used in circuits such as speed regulation of DC motors and dimming of electric lights, with one-way thyristors and two-way thyristors, and the wiring mode is also very flexible and small in size; With the manufacture of high-power thyristors, the application is more extensive; The disadvantage is that the circuit is relatively complex; There are more components.

1. Reduce the voltage by configuring a step-down transformer; The overvoltage protection value can be adjusted to around 425V, or a step-down transformer (output 410V at 420V) can be used as a monitoring voltage for the overvoltage protector.
2. Reverse voltage regulation mode: considering that the voltage loss on the power supply line will increase during the peak load of the power grid, the voltage of the pivot point should be increased to make up for or even offset the increase in voltage loss; When the grid is in low valley load, the corresponding voltage loss on the line is small, and the voltage at the pivot point is reduced to compensate for the reduced voltage loss. This voltage regulation method should be adopted at the pivot point with long power supply line and large load change.
When using reverse regulation, the pivot voltage can be increased to 5% above the rated value during peak loads and reduced to rated values at low load loads.
3. Smooth voltage regulation mode: The so-called smooth voltage regulation mode is to allow the voltage of the pivot point to be slightly lower during peak load and slightly higher at the pivot point voltage during valley load. Contrary to the reverse voltage regulation, the forward voltage regulation method can be used for the pivot point where the power supply line is not long and the load changes are not large.
In general, when the voltage is regulated, the minimum allowable specific rated voltage of the pivot point voltage at peak load is allowed.
The value is high, and the voltage can be higher than the rated voltage value at the time of load valley.
4. Atmospheric voltage regulation mode: The pivot point between the two cases of reverse voltage regulation and forward voltage regulation can be adopted, that is, the voltage of the pivot point can be kept at a basically unchanged value under any load, such as 102% 105% rated voltage.

The most important thing is that the load capacity of the line is not enough, the fundamental solution is to increase the circuit capacity, add new lines, or replace the incoming line with a larger capacity, the voltage regulator can stabilize the fluctuation of the circuit voltage, but can not improve the capacity of the circuit.
-
The load on the regulator should not exceed 50% of the rated capacity, otherwise it will be overloaded. In addition, the ratio of turns of the coil is adjusted.

Summary. The size of the output current of the transformer depends on its coil impedance, the cross-section of the core and the magnitude of the magnetoresistance. There are also factors such as the impedance and output power of the rectifier and voltage stabilizing part; Therefore, in order to increase the output current, it is necessary to replace the transformer with a larger power, and also replace the rectifier and voltage stabilization electronic components. Of course, the output voltage of the transformer and the output voltage of the regulated voltage should be guaranteed to be unchanged at 12V.
If you make your own power supply, you must consider these factors when choosing materials, and match the input requirements of your own electrical appliances in order to use them normally; If you buy a power supply, you only need to see whether the input and output voltage and output current of the power supply can meet the voltage and current requirements of your electrical appliances.

Ways to reduce the voltage drop:
1. Increase the cross-sectional area of the wire, that is, change the wire to a thicker one.
2. Change oxygen-free copper wire or silver wire, that is, reduce the resistivity of the wire.
3. Apply conductive paste at the joint of the wire, that is, reduce the contact resistance.
4. If the transmission is high-frequency AC current, replace the wire with a multi-strand wire, and the thinner each wire is, the better, that is, to reduce the impact of the skin effect.
5. If there are contactors and other electrical components in the circuit, first rule out their causes. Such as poor contact contact, etc.

For most moles, if the patient does not have cosmetic considerations, it is recommended that the patient leave them alone and observe them closely.
