[0002] The inverter is a converter that converts DC power (battery, storage battery) into fixed frequency and voltage or frequency and voltage regulated AC power (usually 220V, 50Hz sine wave). It consists of an inverter bridge, control logic and filter circuit. It is widely used in air conditioners, home theaters, electric grinding wheels, power tools, sewing machines, DVDs, VCDs, computers, televisions, washing machines, range hoods, refrigerators, video recorders, massagers, fans, lighting, etc. In foreign countries, due to the high popularity of cars, inverters can be used to connect batteries to drive electrical appliances and various tools when going out for work or travel. The car inverter output through the cigarette lighter has a power specification of 20W, 40W, 80W, 120W to 150W. A larger power inverter power supply must be connected to the battery through a connecting wire. Connecting household appliances to the output end of the power converter allows you to use various electrical appliances in the car. The electrical appliances that can be used include: mobile phones, laptops, digital video cameras, cameras, lighting, electric shavers, CD players, game consoles, PDAs, power tools, car refrigerators and various travel, camping and medical emergency appliances.
