An inverter is a DC to AC transformer, which is actually a voltage inversion process with a converter.
The inverter is a converter that converts DC electrical energy (batteries, accumulators) into constant frequency, constant voltage, or frequency and voltage regulated alternating current (generally 220V,50Hz sine wave). It consists of inverter bridge, control logic and filtering circuit.
Widely used in air conditioning, home theater, electric grinding wheel, power tools, sewing machines, DVD, VCD, computer, TV, washing machines, range hoods, refrigerators, VCRs, massagers, fans, lighting and so on.
Role
The inverter is to convert DC electrical energy (batteries, storage batteries) into AC power (generally 220v50HZ sine or square wave). In layman's terms, an inverter is a device that converts direct current (DC) to alternating current (AC). It consists of an inverter bridge, control logic and a filter circuit.
Simply put, an inverter is an electronic device that converts low-voltage (12 or 24 or 48 volts) DC to 220 volts AC. It is so called because 220 volts AC is usually rectified into DC for use, while inverters do the opposite, hence the name. In a "mobile" era, mobile office, mobile communication, mobile leisure and entertainment.
