Start-up device with your hands. Start-up device circuit

For motorists, a real battery can become a real problem. It should also be taken into account that it is quite difficult to start a car in winter. In this connection, there is often a need for a start-up charger. To date, many manufacturers are ready to offer this product. The characteristics of chargers are quite different. However, it is possible to make a model of this type absolutely independently. For this purpose, it is necessary to familiarize yourself with the device of the device, as well as to learn its basic configurations.

Scheme of a normal charger

A simple starter-charger circuit includes a threshold transformer and a series of resistors. The coil for instruments is most often used at 20 V. It should also be noted that the models have a damper. It is intended for resonance oscillations. Expanders in chargers are most often installed in a dynamic type. Transistor blocks are used in a variety of ways. To connect the model to the battery, clamps are used, which can vary considerably in shape.

6 V Device

The scheme of the starting-charging device of this type transformer assumes the use of a threshold. However, the first thing to do is to make a solid case for the model. It's quite easy to make it yourself. For this purpose, it became important to select sheets with a thickness of about 2.3 mm. In this case, the foundation must be further strengthened. To do this, many experts recommend using a welding machine to build a base. After that, the transformer is laid. The coil must be located next to it. In this case, the damper is best to select a low-frequency damper.

The output voltage must be at the level of 5 V. It should also be noted that the expanders on the ROM for this type of car are suitable only for dynamic. Capacitors are used field. For their installation, all contacts are first cleaned. Direct soldering of the elements takes place by means of a soldering lamp. At the end of the work, the corresponding clamps are selected for the battery.

How to make a charger for 10 V?

It's quite easy to make such a start-up device with your own hands. In this case, you must first deal with the body of the model. Some make it from the boards. However, in this situation, much depends on the dimensions of the transformer. If we consider threshold analogs, then they weigh a lot. Thus, the base of the device must be strong.

It is also important to make the model transportable. To do this, in the upper part, you need to fix the handles for carrying the device. Transformer in this case it is better to install in the center of the base. After that, the damper is fitted. If we consider linear resonance analogs, then they must withstand the minimum output voltage at the level of 10 V. The vector frequency must oscillate around 44 Hz.

Next, to assemble the device of this type, it is necessary to take the expander. Many in this situation prefer non-condenser modifications. However, in this case, the load on the transistors will be quite large. Fixers for an autonomous starter-charger are better to choose an aluminum type. Corrosion, they are practically not affected.

12 V models

Collect this type of starting-charger with their own hands can be using electrostatic capacitors. Nowadays it's quite easy to get them. For this device in the case it is necessary to make a platform. Before installing the transformer, the sealant must be laid on it. Only then will it be possible to tackle the inductor.

It is selected most often with a primary winding. In this case, the capacitors for the model are more suitable for open type. The output voltage, they are maximum able to withstand at 20 V. It should also be noted that expanders in this case must be installed in the last place. Before doing this, it is important to secure the damper. In some situations, power controllers are also used.

In this case, a good power supply is required. Also it should be noted that it can only be installed with a zener diode. In order to fix the clamps on the device, you can use a welding machine. At the end of the job, it remains only to fix the damper device. It is installed, as a rule, near the transformer. As the instruction says, the starting-charger must be checked for grounding before starting.

Single-phase modifications

To make this type of starting-charger yourself, you will need an integrated transformer. Nowadays these modifications are quite popular among motorcyclists. First of all, when assembling the device, it is recommended to prepare all necessary tools in advance. In particular, for self-manufacturing, a quality welding machine and a soldering lamp along with a set of keys are selected. The starting and charging device 12-24V is made of metal sheets with a thickness of at least 1.4 mm.

In this case, you can simply twist them with screws. After that, it is important to put the rubber seal on the bottom of the case. Next, you will be able to directly install the transformer. To fix it, many experts recommend making a special insert. It represents the U-shaped form of the stop. To do this, you need to take boards about 3.5 cm wide. To properly fix them, you must first measure the body. The next step to the starting and charging device is to install a damper.

In this case, it can be used as a resonant type. The output voltage of this component is required to withstand at 20 V. It should also be noted that the capacitors for the model only buy an open type. At the minimum frequency they are able to maintain at around 45 Hz. At the end of the job it will only be necessary to fix the power supply unit and solder the wires for fixation on the battery.

Two-phase devices

To assemble this type of starting-charger with your own hands, you will need to use a powerful transformer. In this coil, its maximum output voltage is required to withstand at 20 V. The damper for the device is very diverse. In this case, much depends on the type of capacitors. Some experts in this situation prefer open modifications. They are able to serve quite a lot.

Resistors for the device are only suitable integral. Find them in the store simply, but they are worth a lot. Next, to assemble the device, you will need to use a powerful expander. Modifications of the dynamic type in this case are not suitable. Induction models are considered more stable. In order to fix the clamps, it is necessary to use a cable with a diameter of about 0.4 mm.

Three-phase models

Schemes of chargers for car batteries of this type suggest the use of powerful transistor blocks. In order to install them, it is necessary first of all to prepare a site for them. In this case, the body can be built open type without the top. In this case, you can transport the car starter and charger on wheels. Transistors in this situation are selected network type. At least the output voltage they are able to withstand about 15 V.

The frequency parameter of these elements on the average does not exceed 40 Hz. The transformer for the model is selected as a standard threshold type. In this case, the coil should be designed for low frequencies. A damper for a car starter and charger of this type is selected resonant. Install it only on the seal. Some experts additionally install three indicating systems for three-phase modifications. They are necessary in order to look at the panel beyond the level of the output voltage.

Application of pulse transformer PP20

The device diagrams include transformers of the PP20 series, as well as resonance type dampers. Capacitors for this model are suitable only for electrostatic type. Start the assembly of the device with the welding of the substrate. For this purpose, the metal sheets are prepared with a thickness of about 2.2 mm. Coils with a primary winding in this case are used quite often.

At the same time, the display systems are very diverse. In general, the above-mentioned transformer output voltage is able to withstand a level of 15 V. Zener diodes are used only magnetic. Aluminum clamps can be used as fasteners. Conductivity is quite good, but they differ in form. In this case it is better to give preference to small-sized modifications.

Using transformers PP22

Transformers such as PP22 are very common today. Coils are used in this case with a copper winding. The density of them is quite high, and they can serve for a long time. However, the disadvantages of such devices are still available. First of all, it should be noted that the models with this transformer suffer from an increased output voltage. Thus, sudden surges in the network can lead to complete overheating of the capacitors.

Also, resistors often fail. If the display system is installed in the device, the diodes are burned from overvoltage. Install the transformers on the model only with seals. In this case, the tumbler for them is suitable for the P2 series. In turn, indicators are often used in the IN3 class.
