Abstract
A power inverter capable of both DC-AC and DC-DC conversion is disclosed. Said inverter features a novel current mode slope modulation scheme to regulate output while eliminating stability problems commonly held by current mode systems. Furthermore, an embodiment is disclosed utilizing three state modulation to reduce switching losses in the power stage thereby increasing efficiency. Additionally, a novel sine wave compression circuit is disclosed to prevent output wave clipping under low DC supply conditions.
