A voltage converter is a device that is designed to convert the battery's direct electric current into alternating current with certain parameters (50 Hz, 220 V). Such devices often have a thermal protection function, the ability to withstand double overloads and electronic cutoff from the battery in the event of a voltage drop on it.
A 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 power supply. These devices are especially popular in winter, when such accidents happen quite often due to strong winds, icing of wires, heavy snowfalls, etc. Also, winter time is characterized by a power outage due to an excessive number of heaters turned on, due to whichthere is a voltage drop in the supply networks and, as a result, the operation of automatic protection at transformer substations.
The voltage converter has a very wide scope. These devices are used to provide power to yachts and small boats, cars and motor homes, and even in tents on the street during rallies or outdoor recreation. A voltage converter is simply necessary to provide autonomous gas heating. Modern gas boilers are often equipped with electronic control and management circuits, respectively, they will not work when the centralized electricity is turned off. In addition, circulation pumps are installed in the boilers, which also require electricity for their operation. And so that the heating does not turn off when the voltage supply to the network is interrupted, a voltage converter is installed along with the boiler.
During the summer, these devices also do not remain idle, when it is necessary to ensure the smooth operation of refrigeration units and other equipment both at home and in small businesses.
The car converter is very popular, especially when traveling long distances or when going out into the countryside. These devices will help power any technique. A device such as a car voltage converter has small dimensions and low weight, due to the fact that it does not contain a battery, it is connected to the car's on-board network.
The principle of operation of voltage converters: these devices are connected to a 220 V network (except for automobiles), if necessary, they charge the battery connected to them; if the mains voltage fails or falls below 185 V, the device switches to battery mode. The device takes the voltage required for conversion from the battery. Accordingly, the higher the battery capacity, the longer the converter will be able to ensure uninterrupted operation of the devices.
Schemes of such devices belong to medium-complexity circuits, and if you have the skills of practical electronics, you can try to assemble a voltage converter with your own hands.
