Sometimes the battery in the car discharges very quickly. As a result, you have to use various devices in order to start the car. Today, pulsed chargers are very popular. The main producers are considered to be Sonar and Bosch.
However, some people cannot afford to buy these devices because they are expensive. In such a situation, you can try to assemble a model yourself. In order to understand pulse charging, you need to look at the standard circuit of the device.
Scheme of a conventional charging model
Circuit of pulse chargers for car batteries include a transformer with a magnetic circuit, as well as transistors. To adjust the voltage, regulators are used that are connected to the modulators. Also, the pulse charger circuit includes special triggers. Their main task is to increase voltage stability. There are clips on the charger for connecting the device. Electricity itself is supplied through a cable.
6 V device: diagram and instructions
Making a 6V pulse charger yourself is quite simple. For this purpose, a small platform is being constructed for the transformer. It is also necessary to prepare insulators in advance. Directly the transformer is often used power type. The conductivity of the current on average is 6 microns. It is also important to note that the system is able to cope with increased negative resistance. Oscillators are used pulse type.
For normal operation of the device, a linear tetrode is also required. It should be selected with a lining. Some experts strongly recommend the use of filters. Thus, it is possible to stabilize the voltage when the overloads in the network exceed the mark of 20 V. In operation, the instruction of the pulse charger is very simple. To connect the device, clamps are required. In this case, plug the plug into a power outlet.
How to make a charger on 10 V?
Pulse charger circuits for car batteries include step-down transformers. To begin the assembly of the model should be with the search for a quality transformer. In this case, a powerful magnetic circuit is required. Still in the circuit of pulse chargers for batteries include insulators. Many experts install regulators with modulators. Thus, the input voltage index can be reduced or increased. In this case, much depends on the power of the car battery.
Directly tetrodes are used only with plates. Resistors are used expansion type. Some modifications have triggers. These elements allow you to cope with the short-wave interference that occurs in an AC network with a sharp increase in the clock frequency.
12 V Model Reviews
Impulse chargers for 12 V batteries are in great demand these days. If you believe the reviews of experts, then step-down transformers are used to assemble the model. The oscillator in this case will be required with high current conductivity. It is also important to note that only trim triggers are suitable for models.
Tetrodes, in turn, are of a linear type. The parameter of permissible overload in devices does not exceed 15 watts. The rated current index is on average 4 A. Magnetic cores for models are installed behind transformers. Especially for them, it is necessary to choose high-quality insulators. To connect the charger you need clamps. If you believe the experts, you should consider that it will be quite difficult to make them yourself.
Single Phase Modifications
You can make a single-phase pulse charger yourself on the basis of a step-down transformer. Regulators are also used to assemble them. Modulators in this case are suitable only for a switched type. Triggers are installed directly with insulators. Some experts also recommend the use of rubber pads.
Tetrodes are selected with high bandwidth. Regulators are mounted above the modulator. In this case, three resistors are required. They must withstand the rated voltage at around 10 V. Metal clamps will be needed to connect the prior.
Biphasic devices
A two-phase automatic pulse charger is pretty easy to assemble. However, in this situation, you can not do without a power transformer. Also, only expansion resistors are used for assembly. The input voltage in the network, as a rule, does not exceed 12 V. Thyristors for models are used with insulators. The modulator is mounted directly on the lining. The controller in this case is suitable for the rotary type. Magnetic cores are used to overcome interference. Devices of this type are connected through a wire. From a 220 V network, they can also work. To connect to batteries, clamps are required.
Reviews of three-phase modification
Three-phase pulse charger expert reviews are good. The advantage of models is that they can withstand more overload. Magnetic cores in this case are installed with a conductivity of 6 microns. Linear resistors are used to stabilize the output voltage. In some cases, code analogs are also installed. However, their service life is not long.
It is also important to note that the voltage limit in the devices should be regulated using modulators. They are installed right behind the transformers. Trigger triggers are used to overcome magnetic interference. Many experts recommend installing filters to assemble chargers. These elements will help to significantly reduce the negative resistance parameter in the circuit.
Application of pulse transformer PP20
Car chargers (pulse) with these transformers are common. First of all, it should be noted that the indicator of the nominal voltage does not exceed 10 V.The parameter of the operating current is on average 3 A. Oscillators for assembling the device are often used with low conductivity.
Magnetic cores in this case are installed on the pads. Expansion resistors are often used. To adjust the rated voltage, modulators are standardly used. Some modifications use trigger blocks. For the normal operation of the system, one can not do without linear tetrodes. Clamps for the device should be bought separately. Making them yourself is very difficult.
Use of transformers PP22
Chargers (pulsed) with these transformers are quite common. In order to assemble the modification yourself, you will need to find a high-quality oscillator. Also, the transformer will only work with a 3 micron core. In this case, expansion resistors are most suitable. However, first of all, it is important to do 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 tackle 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 rated voltage will be around 5 V. The operating current is approximately 4 A.
Charging equipment with transformer PP30
In order to assemble chargers (pulse) with the indicated transformers, a powerful magnetic circuit is required. In this case, the oscillator is more appropriate to use at 2 microns. The negative resistance parameter in the circuit must be higher than 3 ohms. A magnetic circuit is installed next to the transformer. To connect the modulator will require two contacts. It is also important to note that it is more advisable to use regulators of a rotary type.
Many experts recommend installing resistors on the lining. All this will significantly reduce the occurrence of short circuits. To stabilize the voltage, filters are standardly used. Trigger blocks with these zoom lenses are most often used for the tuning type. However, in our time it is difficult to find them. Most often it comes across operational counterparts. They can withstand rated voltage in the circuit at 15 V.
Application of isolation transformers
Isolation 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 on code resistors that 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 machine. Thyristors in this case are used only wave type. They are installed most often on the plates. An insulator is used to solder the modulator. Transistors many experts strongly recommend using a semiconductor type. In the store they are presented with different conductivity. As a result, the parameter of negative resistance in the circuit should not exceed 8 ohms. Clips are used to connect the device to car batteries.
Model with transformer KU2
Transformers of this series have large dimensions and are able to work only with 4 micron cores. All this suggests that triggers will be required for normal operation of the device. Using these devices will stabilize the output voltage. Also, near the transformers you will need to install two filters. Some experts strongly recommend the use of zener diodes. However, these devices are only able to work with little network congestion.
In this case, the resistors can be safely applied to the expansion type. To adjust the output voltage, switched modulators are used. The regulators should be installed directly through the throttle. If you believe the expert reviews, then the transformer for safe use should be lined. In this case, two isolators will be required. The transistor is most often used semiconductor type.
Charging equipment with transformer KU5
Chargers (pulse) with these transformers are not in great demand. This is primarily due to the low output voltage. Thus, charging a car battery takes a lot of time. However, if you use a powerful oscillator, then the situation can be slightly corrected. Also, many experts recommend installing expansion resistors.
In this case, the modulator is suitable only for a switched type. Some models have unipolar zener diodes. However, in this situation, the transformer may not withstand excessive loads. The trigger is often applied trimming type. To combat shortwave interference, you can not do without filters. To connect the device to the car battery use clamps.
Dual Choke Model
Chargers (pulse) with dual chokes allow you to use more than two modulators. Thus, it is possible to install digital voltage regulators. In this case, the transformers are most often selected lowering type. Oscillators are used directly at 3 microns. Resistors, many experts recommend installing an expansion type. In turn, code analogs will not be able to last long. Thyristor blocks are used both wave and operational type.
