The subject invention reveals new three terminal tapped inductor canonical cells for non-isolated power conversion. The canonical cells achieve reduced semiconductor component stresses for applications with limited line voltage range for small step up and step down ratios or for large step up and step down ratios. Some of the canonical cells can be used to form buck, boost, and buck boost converters. Another of the canonical cells is a member of the SEPIC family which can both step up and step down or operate in all four quadrants. Related canonical cells which achieve zero voltage switching and improved electromagnetic compatibility are also revealed. A new more robust floating gate drive control circuit is revealed which operates without magnetic components, without optical coupling, and without high voltage semiconductors is revealed.
