Abstract
An apparatus providing a source of alternating power for power devices is disclosed. The apparatus comprises a frame member having a plurality of ground engaging wheels for transporting the frame member along the ground. The frame member carries a plurality of DC storage means therein. A transformer means carried on the frame has a low voltage center tapped winding, a line voltage winding, and a high voltage winding. The low voltage center tapped winding is in communication with the DC storage means, and the line voltage winding is operable to produce an AC output voltage suitable for powering devices. A plurality of controllable rectifier means is in communication with both the high voltage winding and the low voltage center tapped winding. The rectifier means are operable to alternately provide a conduction path for said DC storage means through both halves of the low voltage center tapped winding.
