In one simple inverter circuit, DC power is connected to a through the center tap of the primary winding. A switch is rapidly switched back and forth to allow current to flow back to the DC source following two alternate paths through one end of the primary and then the other. The alternation of the direction of current in the primary winding of the transformer produces

The three general categories of modern UPS systems are on-line, line-interactive and standby: • An online UPS uses a "double conversion" method of accepting AC input, to DC for passing through the (or battery strings), then inverting back to 120 V/230 V AC for powering the protected equipment.

An inverter converts the DC electricity from sources such as or to AC electricity. The electricity can be at any required voltage; in particular it can operate AC equipment designed for mains operation, or rectified to produce DC at any desired voltage. An (UPS) uses batteries and an inverter to suppl.

A power inverter, inverter, or invertor is a device or circuitry that changes (DC) to (AC). The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of which were originally large electromechanical devices converting AC to DC.
