The following is the circuit diagram of [12V to 220V inverter circuit ]

Inverter converts DC power (battery, battery) into alternating current (typically 220V, 50Hz sine wave). It consists of an inverter bridge, control logic and filter circuits. Widely used in air conditioners, home theaters, electric grinding wheels, power tools, sewing machines, DVD, VCD, computers, televisions, washing machines, range hoods, refrigerators, video recorders, massagers, fans, lighting, etc. In foreign countries, because of the high penetration rate of automobiles, you can use the inverter to connect the battery to drive electrical appliances and various tools. The on-board inverter output through the cigarette lighter is 20W, 40W, 80W, 120W to 150W power specifications. More power inverter power supplies are connected to the battery through the cable. Connecting appliances to the output of the power converter allows for the use of various appliances in the car. The appliances that can be used include: mobile phones, notebook computers, digital video cameras, cameras, lights, electric razors, CD players, game consoles, PDAs, power tools, car refrigerators, and various travel, camping, medical emergency appliances.
