Through the inverter group, the direct current into 50~60Hz single-phase alternating current. And then through the autocoupled Woodbridge balancing transformer (AWB) will be two groups of single-phase alternating current into three-phase alternating current, sent to the power grid. This large-capacity balancing transformer not only has the function of transformer and current, but also has the function of phase change. Its efficiency is above 99%, and its relative material utilization rate reaches 100%.
Expanded Information
The inverter is a device that converts DC power (batteries, storage batteries) into AC power (generally 220V,50Hz sine wave). It consists of inverter bridge, control logic and filter circuit. Widely used in air conditioning, home theater, electric grinding wheel, power tools, sewing machines, DVD, VCD, computers, TV, washing machines, range hoods, refrigerators, VCRs, massagers, fans, lighting and so on. In foreign countries, due to the high popularity of automobiles, you can use the inverter to connect the battery to drive electrical appliances and various tools. The car inverter output through the cigarette lighter is 20W, 40W, 80W, 120W to 150W power specifications. Larger power inverters should be connected to the battery through the connecting cable. By connecting household appliances to the output of the power converter, you can use all kinds of electrical appliances in the car. The electrical appliances can be used: cell phones, notebook computers, digital video cameras, cameras, lights, electric shavers, CD players, game consoles, PDAs, power tools, car refrigerators, and a variety of travel, camping, medical emergency appliances and so on.
