Voltage converter: purpose, description

The voltage converter is a device that is designed to convert the DC electric current of the battery into alternating current with certain parameters (50 Hz, 220 V). Such devices often have a function of temperature protection, the ability to withstand double overloads and electronic cut-off from the battery in the event of a voltage drop on it.

Voltage converter is often used to ensure the uninterrupted operation of household appliances (computer, TV, refrigerator, gas boiler, etc.) in the event of an emergency or planned shutdown of the centralized supply of electricity. Especially popular are these devices in the winter, when such accidents happen quite often due to strong winds, freezing of wires, heavy snowfalls, etc. Also, winter time is characterized by power outages due to the excessive number of heating devices that are switched on, because of which there is a voltage drop in the supply networks and, as a consequence, automatic protection operation on transformer substations.

The voltage converter has a very wide scope. These devices are used to provide power supply for yachts and small boats, cars and houses on wheels, and even in tents on the street during rallies or outdoor recreation. The voltage converter is simply necessary to provide autonomous gas heating. Modern gas boilers are often equipped with electronic control and control schemes, respectively, they will not work when switching off centralized electricity. In addition, circulating pumps are installed in the boilers, which also require electricity for their work. And so that the heating does not turn off when the power supply fails, a voltage converter is installed together with the boiler.

In summer, these devices also do not remain without work, when it is required to ensure the uninterrupted operation of refrigeration equipment and other equipment both at home and in the small business.

The automobile converter is very popular, especially when traveling to a long distance or when traveling to nature. These devices will help to supply any equipment. Such a device as an automobile voltage converter has small dimensions and low weight, due to the fact that it does not have a rechargeable battery, it is connected to the vehicle's on-board network.

The principle of the voltage converters: these devices are connected to the 220 V network (except for automobile ones), if necessary they charge the battery connected to them; If the mains voltage drops or falls below 185 V, the device switches to battery mode. The device required for conversion is taken from the battery. Accordingly, the higher the battery capacity, the longer it will be able to ensure trouble-free operation of the instrument converter.

The circuits of such devices are related to medium complexity circuits, and if you have the skills of practical electronics - you can try to assemble the voltage converter yourself.
