The converter of voltage 12-220. Voltage converter with own hands

Voltage converters 12-200 V in our timequite strongly in demand. With their help, drivers have the opportunity to use household appliances right in the car. However, it should be noted that these devices are quite expensive. To solve this problem, many are trying to assemble a simple converter of 12-220 V.

Accessories can be used different. In order not to burn the wiring in the car, it is necessary to follow the assembly instructions carefully. However, first of all you should familiarize yourself with the scheme of a simple converter.

Converter circuit

A simple 12-220 V converter circuit incorporatesself electrical coil, transformer, tetrode and resistors. In this case, the rectifiers are of varying frequency. In some cases, filters are used to stabilize the voltage. Current regulators are not equipped with all models. Amplifiers of inertial type are often used. However, in this case, much depends on the manufacturer. If we talk about the 12-220 converter at 50 A, then it additionally sets the resonators, which are necessary for the generation of pulses.

Transformers with operating rectifiers

Assemble this type of converter 12-220with their own hands is quite simple. First of all, a coil with a primary winding is selected. Resistance, it must withstand at 30 ohms. To change the phase, a transformer is used. Directly the rectifier is installed next to the tetrode.

Resistors many specialists in 12-220the converter is advised to select an open type. Amplifiers in this case can not be installed. However, if you add the model to 60 A, then they should be soldered near the inductive coil. At the end of the job, you only need to secure the terminal blocks.

Model with phase rectifiers

Converter 12-220 for home with phaseThe rectifier is folded only with the participation of an inductor of 40 Ohm. In this case, thyristors should be selected chromatic. It is also important to pay attention to the transformer. Some experts advise using lowering models, however it is rather difficult to find them on the market. Thus, many still use standard power modifications. The amplifier in this case will only need one. A choke is used to connect the transformer to the tetrode.

To increase the conductivity of the current, manyrecommend installing resonators. The limit voltage on the transformer should be checked with a tester. To ensure that the tetrode does not burn out quickly, it is recommended to use a zener diode. In this case, you can select it in the store for two contacts. At the end of the operation it is important to fix the terminal blocks in the 12-220 converter.

The use of amplifiers

Amplifiers on the market are represented mainlytwo-channel. By their parameters, they can be quite different. In this case, it is more expedient to select modifications with high conductivity. It should also be borne in mind that they must withstand the limiting voltage in 220 V. Start the assembly of the converter with the installation of an induction coil. To do this, make a special platform that does not pass current. In this situation, you can use a plain board.

After fixing the coil, it is important to immediately installtransformer. The amplifier in the 12-220 converter is soldered behind the tetrode. Two filters are required to stabilize the voltage. However, in this case, much depends on the selected amplifier.

Devices on a double resistor

On a double resistor converter 12-220(the diagram is shown below) is quite rare. The problem in this case lies in the sharp jumps in the frequency. Thyristors for assembly should be used in a down-type. To reduce the amplitude of the interference, it is recommended that the coil be installed after the rectifier.

Filters for the converter can be easily selectedgrid type. In some cases, regulators are used to control the frequency. In addition, a display system must be installed for the inverter. Terminal blocks in this situation are required to be fixed at the output of the transformer.

Using the transceiver

Make transducer 12-220 with transceiverwith their own hands is easiest, if you use a step-down transformer. In this case, the rectifier is suitable for operating type. Total amplifiers for the system need three. One of them is installed immediately behind the inductor. In this case, two other amplifiers must be used behind the transformer. The filter for the model will need one. The transceiver to the converter is connected via a throttle.

To increase current conductivity, many expertsrecommend using zener diodes. In this situation, the frequency controller needs to be set if the coil is available at 50 A. Otherwise, there is no need to distribute the load. Secure the work of the transformer to the full extent can filter.

Transducers with two-digit dinistors

This type of converter 12-220 (circuitshown below) must be assembled on the basis of only pulse transformers. To ensure that the voltage does not drop sharply, it is important to choose a quality inductor of 30 A. Next, you need to install an amplifier for the assembly.

If we consider an inductor at 30 A,it can be of inertial type. The rectifier in this situation must be located behind the amplifier. To the coil is not overheated, many experts recommend using zener diodes. Regulators for this model are not needed.

The device on three-digit dinistors

Three-digit dinistors can be combined only withconvection transformer. In this case, two coils should be used. To select them should be 20 A. To minimize the sudden jumps in the system, it is important to install a filter next to the transformer. Some in this situation also use fuses. Thyristors need to be installed behind the inductor. Regulators for these models are needed.

Good for the converter rotarymodification. Directly connect them through the throttle. In some cases, these devices are characterized by poor conductivity. This is due to a malfunction in the transformer. You can solve the problem by replacing the thyristor.

Using rectifiers 1N4148

Rectifiers of this type are capable of operating onlywith step-down transformers. In this situation, the assembly of the converter should begin with the installation of an induction coil. It is more expedient to select it for 50 A. In this case, the filters in the device require only two. One of them must be located behind the thyristor.

The second filter should be installed next totransformer. The frequency of the model can be adjusted thanks to the regulator. Bipolar amplifiers for transducers are used very rarely. Directly the terminal blocks should be installed last. Zener d in this case is not required. To ensure that the resistor does not burn out, it is necessary to install a fuse. The maximum voltage it is required to withstand at 220 V.

Model on SF16 rectifiers

These rectifiers are very much appreciated for their quality. With the conductivity of the current they are all good. However, it should be taken into account that a power transformer is installed in this voltage converter 12-220 V. All this means that without a trigger the system will not work. In order to minimize sharp current surges in the network, filters are used as standard. The regulator should be installed only if the coil is selected for the model by 60 A. Otherwise, it will only spend electricity.

The rectifier is soldered in the circuit behind the trigger. In some cases, operational amplifiers are additionally installed in the 12-220 V voltage converter. In this situation, the absorbing filters will significantly increase the load on the transformer. The terminals at the converter should be placed at the output of the circuit.
