The inverter is the conversion of DC energy (batteries, storage battery) into alternating current (usually 220v50hz sine or square wave). In layman's words, an inverter is a device that converts direct current (DC) into alternating current (AC).
It consists of an inverter bridge, a control logic and a filter circuit.
Widely used in air-conditioning, home theater, electric grinding wheel, power tools, sewing machine, DVD, VCD, computer, TV, washing machine, range hood, refrigerator, VCR, massager, fan, lighting and so on. Simply put, the inverter is an electronic device that transforms a low-voltage (12 or 24-volt or 48-Volt) DC into a 220-volt alternating current. Because we usually use 220 volts alternating current rectifier to DC, and the effect of the inverter is the opposite, hence the name. We are in a "mobile" era, mobile office, Mobile communications, mobile leisure and entertainment. In the moving state, people need not only the low-voltage direct current which is supplied by the battery or batteries, but also the 220 volts alternating current which we need in the daily environment, the inverter can meet our demand.
