The magnetic cores of the models are installed behind the transformers. Especially for them, it is necessary to select high-quality insulators. Clamps are required to connect the charger. If you believe the experts, then you should take into account that it will be quite difficult to make them yourself.
Single-phase modifications
You can make a single-phase pulse charger with your own hands based on a step-down transformer. Regulators are also used to assemble them. Modulators in this case are suitable onlyswitched type. Directly triggers are installed with insulators. Some experts also recommend using rubber pads.
Tetrodes are selected with high bandwidth. Regulators are installed above the modulator. Resistors in this case will need three. They must withstand the rated voltage at around 10 V. To connect the prior, you will need metal clamps.
Two-phase devices
The two-phase automatic pulse charger is quite easy to assemble. However, in this situation, a power transformer cannot be dispensed with. Also, only expansion resistors are used for assembly. The input voltage indicator in the network, as a rule, does not exceed 12 V. Thyristors for models are used with insulators. The modulator is directly installed on the lining. The regulator in this case is suitable for rotary type. Magnetic circuits are used to overcome interference. Devices of this type are connected via a wire. They can also work from a 220 V network. Clips are required to connect to batteries.
Reviews on the three-phase modification
Three-phase switching charger reviews from experts are good. The advantage of models is that they are able to withstand more overload. In this case, the magnetic circuits are installed with a conductivity of 6 microns. Linear resistors are used to stabilize the output voltage. In some cases, code analogues are also installed. However, they do not have a long service life.
It is also important to note thatthe limit voltage in the devices should be regulated using modulators. They are installed right behind the transformers. Trimmer triggers are used to overcome magnetic interference. Many experts for assembling chargers recommend installing filters. These elements will help to significantly reduce the negative resistance parameter in the circuit.
Use of PP20 pulse transformer
Car chargers (pulse) with these transformers are common. First of all, it should be noted that their nominal voltage does not exceed 10 V. The operating current parameter is on average 3 A. Oscillators for assembling the device are often used with low conductivity.
Magnetic cores in this case are installed on pads. Expansion resistors are used frequently. To adjust the rated voltage, modulators are used as standard. Some modifications use trigger blocks. For the normal operation of the system, linear tetrodes are also indispensable. It is better to buy clamps for the device separately. Making them yourself is very difficult.
Using PP22 transformers
Chargers (pulse) with these transformers are quite common. In order to independently assemble a modification, you will need to find a high-quality oscillator. Also the transformer willwork only with a 3 micron magnetic circuit. In this case, expansion type resistors are most suitable. However, first of all, it is important to deal with the installation of the regulator. For this purpose, you need to use a switched modulator, which is installed on the lining.
Next, it is important to deal with the semiconductor transistor. In order to avoid short circuits, many experts recommend the use of stabilizers. There are many single-pole modifications on the market. In this case, the nominal voltage will be around 5 V. The operating current is approximately 4 A.

In order to assemble chargers (pulse) with the indicated transformers, you will need a powerful magnetic circuit. In this case, it is more expedient to use the oscillator at 2 microns. The negative resistance parameter in the circuit must be above 3 ohms. A magnetic circuit is installed next to the transformer. Two pins are required to connect the modulator. It is also important to note that it is more expedient to use rotary type regulators.
Many experts recommend installing resistors on the plate. All this will significantly reduce the cases of short circuits. Filters are commonly used to stabilize the voltage. Trigger blocks with these zooms are most often used as a trimmer type. However, they are hard to find these days. Most often, it is operational analogues that come across. Rated circuit voltage they are capable ofwithstand at 15 V.
Use of isolating transformers
Isolating transformers are very rare. Their main problem lies in the low conductivity of the current. It is also important to note that they can only work with code resistors, which are expensive in the store. However, the models have advantages. First of all, this concerns the increased rated voltage in the circuit. Thus, charging a car battery will not take much time.
It should also be noted that these transformers are compact and will not take up much space in the car. Thyristors in this case are used only of the wave type. They are most often installed on the plates. An insulator is used to solder the modulator. Transistors many experts strongly recommend using the semiconductor type.
