A voltage converter is a device that is designed to convert a constant electric current from a battery into alternating current with certain parameters (50 Hz, 220 V). Such devices often have the function of thermal protection, the ability to withstand double overload and electronic cutoff from the battery in case of voltage drop on it.
A voltage converter is often used to ensure the uninterrupted operation of household appliances (computer, television, refrigerator, gas boiler, etc.) in the event of an emergency or planned outage of the centralized power supply. These devices are especially popular in the winter, when such accidents happen quite often due to strong winds, icy wires, heavy snow, etc. Also, winter time is characterized by a blackout due to an excessive number of turned on heating devices, due to which a voltage drop occurs in the supply networks and, as a result, automatic protection trips 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 meetings or outdoor recreation. A voltage converter is simply necessary to provide autonomous gas heating. Modern gas boilers are often equipped with electronic control and control 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 power supply is cut off, a voltage converter is installed with the boiler.
In the summer, these devices also do not remain without work when it is required to ensure the uninterrupted operation of refrigeration units and other equipment both at home and in the small business.
The automobile converter is very popular, especially when traveling long distances or when going out into the countryside. These devices will help power any equipment. Such a device as an automotive 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 operation of voltage converters: these devices are connected to a 220 V network (except automotive), 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 takes the voltage required for conversion from the battery. Accordingly, the higher the battery capacity, the longer the converter can provide uninterrupted operation of the devices.
The circuits of such devices relate to circuits of medium complexity, and if you possess the skills of practical electronics, you can try to assemble a voltage converter with your own hands.
