A Power Inverter is a power electronic device or circuit that alters direct current (DC) to alternating current (AC). The resultant AC frequency obtained depends on the specific device employed. The core function of a power inverter is to alter DC power into standard AC. It is due to; while AC is the power provided to industries and homes by the core public utility or power grid, the batteries of AC systems store only direct current power.
Their general applications contain portable user devices that let the user attach a set of batteries or a single battery to the device to provide AC power to run different electrical gadgets or devices like power tools, kitchen appliances, television, and lights. If you are thinking of buying a power inverter, go for the Acer LCD Board Inverter for Aspire 5585 5583, Dell CCFL Inverter for Latitude E6400, and IBM Lenovo SXGA Inverter for ThinkPad T60.
