Depending on wattage and input voltage levels, GTIs circuits normally have from one to three stages. A conceptual power train schematic diagram below illustrates the principles of operation of a three-stage grid tie inverter.

Its principle of operation is based on the alternating closure and disconnection of power electronic switching devices, thus converting the DC supply voltage into a series of pulsed voltages, which are then converted into stabilized AC power through a filter.
