Often, an inverter is used to connect a laptop, printer, scanner and other gadgets to the on-board car network. Often there is a need to connect a small refrigerated truck, a powerful compressor for inflating tires, a drill or an angle grinder to the on-board car network.
The use of an inverter makes it possible to use a microwave oven, hair dryer, vibration massager and other practical devices on the road. The inverter makes it possible to connect any electrical or electronic device to the on-board car network that requires a variable current intensity of 110/220 volts.
When it is necessary to change the AC voltage, one converter with initial and repeated winding is enough. With continuous electricity, everything is not so easy - the car enthusiast needs a more difficult electrical circuit with semiconductor components.
In the case under consideration, it is necessary to increase the voltage and transform its form. For this purpose, a mixed circuit is used, in which both converter and semiconductor devices are used.
The basis of pulse width modulation is the principle of operation of the inverter. The main generator delivers shocks, the frequency of which ranges from 10 kHz to 20 MHz, to a power switch connected to the winding of the induction converter - alternating current is removed from its output.
The width of the shocks is determined by the connected load, and therefore the circuit uses a feedback structure.The smallest duty cycle of the signals is equal to the minimum power, and with an increase in the output current, the width of the shock reaches 1:1 (limiting value).
The difficulty lies in the fact that the type of output signal that is obtained in this case is not a plastic decrease / increase in voltage (graph), but a square wave with a sharp change in potential.
This means that the measured voltage cannot be applied to various electronic devices. To convert a square wave into a sine wave, the inverter circuit is supplemented with filters from capacitors and coils.
Inverters for cars are divided into 2 types:
Power rectifiers are divided into:
It is worth giving preference to such an inverter for a 12/220V car, so that it has a power reserve. For example, certain gadgets may consume more resources than indicated by the manufacturer.
Today, there are many different types of inverters for a car, differing in type, power method and power. Low-power rectifiers differ in power no more than 300 watts. They are used to charge phones or laptops. This type of inverter for a car is inserted into the cigarette lighter socket.

Proper installation, connection and subsequent use are a guarantee of a long and successful operation of the inverter. In order not to be disappointed in the acquisition, follow the principles listed below:
Like any modern device, the inverter for the car is equipped with a specialized protective tool that protects it from failures or malfunctions and voltage failures of more than 12 V.
The auto-shutoff feature protects against overload and is instantly activated during a power failure. In the event of a short circuit, the device will also turn off.
When purchasing an inverter, consider:
In conclusion, it is worth noting that when buying a converter, you should not forget that 12 and 24 V inverters are not interchangeable, unless it is indicated on the device shell and in its user manual.
Connecting a 12-volt converter to a 24-volt battery leads to overheating and operational failure of the main transistors and other components due to overvoltage.
Connecting a 24-volt converter to a 12-volt battery causes hot flash and failure of the main transistors due to the excessive duty cycle of collector surges.
