Voltage converters 12-200 V in our time are pretty much in demand. With their help, drivers have the opportunity to use household appliances directly in the car. However, it should be noted that these devices are quite expensive. To solve this problem, many try to assemble a simple 12-220 V converter on their own.
Accessories can be used various. In order not to burn the wiring in the car, you should strictly adhere to the assembly instructions of the device. However, first of all, you should familiarize yourself with the circuit of a simple converter.
Converter circuit
A simple 12-220 V converter circuit includes an electric coil, a transformer, a tetrode, and resistors. In this case, rectifiers are used at different frequencies. In some cases, filters are used to stabilize the voltage. Not all models are equipped with current regulators. Inertial amplifiers are often used. However, in this case, much depends on the manufacturer. If we talk about a 12-220 50 A converter, then it additionally installs resonators, which are necessary for generating pulses.
Converters with operational rectifiers
To assemble this type of converter 12-220 with your own hands is quite simple. First of all, a coil with a primary winding is selected. Resistance is required to withstand at 30 ohms. A transformer is used to change the phase. The rectifier is mounted directly next to the tetrode.
Resistors many experts in the 12-220 converter are advised to select an open type. Amplifiers in this case can not be installed. However, if the model is folded at 60 A, then they should be soldered near the inductive coil. At the end of the work, you only need to fix the terminal blocks.
Model with phase rectifiers
The converter 12-220 for a house with a phase rectifier develops only with the participation of an inductance coil of 40 Ohms. 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. An amplifier in this case will require only one. A choke is used to connect the transformer to the tetrode.
To increase current conductivity, many recommend installing resonators. The transformer limit voltage should be checked with a tester. In order for the tetrode to not quickly burn out, 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 in the 12-220 converter.
Amplifier Application
Amplifiers on the market are mainly two-channel. In 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 maximum voltage of 220 V. The assembly of the converter should be started 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 an ordinary tablet.
After fixing the coil, it is important to install the transformer immediately. The amplifier in the 12-220 converter is soldered behind the tetrode. To stabilize the voltage, two filters are required. However, in this case, a lot depends on the selected amplifier.
Dual resistor devices
On a dual resistor, a 12-220 converter (circuit shown below) is quite rare. The problem in this case lies in sharp frequency jumps. Thyristors for assembly should use a step-down type. To reduce the amplitude of interference, it is recommended to install the coil after the rectifier.
Filters for the converter can be safely selected mesh type. In some cases, controllers are used to control the frequency. Additionally, an indicator system should be installed for the transmitter. Terminal blocks in this situation are required to be mounted as standard at the output of the transformer.
Using a transceiver
Making the 12-220 in-house converter with a transceiver the easiest way is to use a step-down transformer. In this case, the rectifier is suitable for the operating type. Total amplifiers for the system need three. One of them is installed directly 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 is connected to the converter via a choke.
To increase the current conductivity, many experts recommend the use of zener diodes. In this situation, the frequency regulator must be installed if the coil is at 50 A. Otherwise, there is no need to distribute the load. The transformer will be able to fully secure the operation of the filter.
Converters with two-digit dinistors
This type of converter 12-220 (the diagram is shown below) must be assembled on the basis of only pulse transformers. In order for the ultimate voltage not to drop sharply, it is important to choose a high-quality inductor of 30 A. Next, an amplifier should be installed for assembly.
If we consider an inductor at 30 A, it can be used inertial type. The rectifier in this situation must be located behind the amplifier. To prevent the coil from overheating, many experts recommend the use of zener diodes. Regulators for this model are not needed.
Three-digit dinistor device
Three-digit dinistors can only be folded 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 needed.
Rotary modifications are well suited for the converter. Directly connecting them should be through a 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 can only work with 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 at 50 A. In this case, there will be only two filters 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 knob. Bipolar amplifiers for converters are used very rarely. The terminal blocks themselves should be installed last. Zener diodes in this case are not required. In order for the resistor not to blow, it is necessary to install a fuse. He must withstand the maximum voltage at 220 V.
Rectifier Model SF16
These rectifiers are very much appreciated for their quality. With current conductivity, they are all well. However, it should be borne in mind that a power transformer is installed in this voltage converter 12-220 V. All this suggests that without a trigger the system will not work. To minimize sudden surges in current in the network, filters are standardly used. The regulator must be installed only on condition that the coil is selected for the model at 60 A. Otherwise, it will only consume electricity.
The rectifier in the circuit is soldered 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 terminal blocks at the inverter should be placed at the circuit output.
