Abstract
Bidirectional power conversion systems provide the ability to change power attributes to and from a component. Current bidirectional power conversion systems use a unidirectional power converter for each direction. The integration of the two normally independent power converters results in a bidirectional power converter with nearly half the size, weight, volume, cost and complexity. Described are embodiments of bidirectional power conversion systems that allow power transfer between two or more components without requiring the use of separate unidirectional power converters.
Claims5
1-37. (canceled)
A driver circuit that controls the switching of at least two power switches in a bidirectional power converter, said at least two power switches that intermittently connect at least two power buses to a reactive element.
The driver circuit of claim 29, said driver circuit comprising at least one level shifter that receives at least said selection signal, said level shifter that increases the voltage level of said selection signal prior to providing said selection signal voltage level to said first and second anti-cross conduction circuits.
