Voltage converters 12-200 V in our time are quite 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 12-220 V converter on their own.
Various components can be used. In order not to burn the wiring in the car, you should strictly follow the instructions for assembling the device. However, first of all, you should familiarize yourself with the diagram of a simple converter.
Converter circuit
A simple 12-220V converter circuit includes an electric coil, transformer, tetrode, and resistors. In this case, rectifiers are used with different frequencies. In some cases, filters are used to stabilize the voltage. Not all models are equipped with current regulators. Amplifiers of inertial type are often used. However, in this case, a lot depends on the manufacturer. If we talk about a 12-220 converter for 50 A, then resonators are additionally installed in it, which are necessary for generating pulses.
Converters with operating rectifiers
It is quite simple to assemble this type of 12-220 converter with your own hands. First of all, a coil with a primary winding is selected. It must withstand resistance at the level of 30 ohms. A transformer is used to change the phase. The rectifier is installed directly next to the tetrode.
Many specialists in the 12-220 converter advise resistors to select an open type. In this case, amplifiers can be omitted. However, if the 60A model is folded, then they should be soldered near the inductive coil. At the end of the work, you only need to fix the terminal blocks.
Phase rectifier model
The 12-220 home converter with phase rectifier folds only with 40 ohm participation. In this case, thyristors should be selected chromatic. It is also important to pay attention to the transformer. Some experts advise using lowering models, but finding them on the market is quite difficult. Thus, many still use standard power modifications. In this case, only one amplifier is required. A choke is used to connect the transformer to the tetrode.
To increase current conductivity, many people recommend installing resonators. The limit voltage on the transformer should be checked with a tester. In order to prevent the tetrode from burning out quickly, it is recommended to use a zener diode. In this case, it can be selected in the store for two contacts. At the end of the work, it is important to fix the terminal blocks at 12-220 converter.
Application of amplifiers
Amplifiers on the market are mainly two-channel. In terms of 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 limit voltage of 220 V. The assembly of the converter should be started with the installation of an induction coil. For this, a special platform is made that does not pass current. In this situation, you can use a regular board.
After securing the coil, it is important to install the transformer immediately. The amplifier in the 12-220 converter is soldered behind the tetrode. Two filters are required to stabilize the voltage. However, in this case, a lot depends on the chosen amplifier.
Dual resistor devices
On a double resistor, a 12-220 converter (the diagram is shown below) is quite rare. The problem in this case lies in the sharp jumps in frequency. Thyristors for assembly should be of the step-down type. To reduce the amplitude of the interference, it is recommended to install the coil after the rectifier.
Filters for the converter can be safely selected mesh type. In some cases, knobs are used to control the frequency. Additionally, a display system must be installed for the transmitter. In this situation, the terminal blocks must be standardly attached at the output of the transformer.
Using the transceiver
It is easiest to make a 12-220 converter with your own hands with a transceiver, if you use In this case, an operational type rectifier is suitable. In total, three amplifiers are needed for the system. One of them is installed immediately behind the inductor. In this case, the other two amplifiers must be used behind the transformer. One filter is required for the model. The transceiver is connected to the converter through a choke.
Many experts recommend using zener diodes to increase current conductivity. In this situation, the frequency regulator must be set if the coil is available for 50 A. Otherwise, there is no need to share the load. The filter can fully secure the operation of the transformer.
Converters with two-digit dinistors
This type of converter 12-220 (the diagram is shown below) must be assembled on the base only.In order that the limit voltage does not drop sharply, it is important to select a high-quality inductor for 30 A. Next, an amplifier should be installed for assembly.
If we consider a 30A inductor, it can be used an inertial type. The rectifier in this situation must be located behind the amplifier. To prevent the coil from overheating too much, many experts recommend using zener diodes. Regulators are not needed for this model.
Three-bit dinistor device
Three-digit dinistors can only be stacked with a convection transformer. In this case, two inductors should be used. They should be selected at 20 A. To minimize sudden surges in the system, it is important to install a filter near the transformer. Some also use fuses in this situation. Thyristors must be installed behind the inductor. Regulators for these models are required.
Rotary modifications are well suited for the converter. Their direct connection must be carried out through a choke. In some cases, these devices are characterized by poor conductivity. This happens due to transformer malfunctions. The problem can be solved by replacing the thyristor.
Using rectifiers 1N4148
Rectifiers of this type are capable of working only with step-down transformers. In this situation, the assembly of the converter should be started by installing the induction coil. It is more expedient to select it at 50 A. In this case, only two filters are required in the device. One of them must be located behind the thyristor.
The second filter will need to be installed next to the transformer. The frequency of the model can be adjusted thanks to the regulator. Bipolar amplifiers for converters are used very rarely. The terminal blocks should be installed last. Zener diodes are not required in this case. In order to prevent the resistor from blowing out, it is necessary to install a fuse. It must withstand the limiting voltage at the level of 220 V.
Rectifier model SF16
These rectifiers are highly regarded for their quality. They are doing well with current conductivity. However, it should be borne in mind that 12-220 V is installed in this voltage converter. All this suggests that the system will not work without a trigger. Filters are used as standard to minimize power surges. The regulator should only be installed if the coil is matched to the 60A model, otherwise it will only consume electricity.
The rectifier is soldered in the circuit behind the trigger. In some cases, a 12-220 V voltage converter is additionally installed. In this situation, absorbing filters will significantly increase the load on the transformer. The terminal blocks at the converter should be located at the circuit output.
