Abstract
An inverting apparatus comprises: a DC port; an AC port; five switches; a first capacitor coupled between the first terminal of the second switch and the second terminal of the fourth switch; and a free-wheeling element coupled between the second terminal of the third switch and the second terminal of the fifth switch; wherein the five switches are controlled so that the device can switch among a plurality of operating modes and transmit active or reactive power to a power grid.
