Power regulator and power conversion circuitry for delivering power

Abstract:

A DC-to-DC transformer converts power from an input source to a load using a fixed voltage transformation ratio. The density of point of load power conversion may be increased and the associated power dissipation reduced by removing the input driver circuitry from the point of load where it is not necessary. An output circuit may be located at the point of load providing fault tolerant rectification of the AC power from the secondary winding of a power transformer which may be located nearby the output circuit. The driver circuit may drive a plurality of transformer-output circuit pairs. The transformer and output circuit may be combined in a single module at the point of load. Alternatively, the output circuit may be integrated into point of load circuitry such as a processor core. The transformer may be deployed near the output circuit.
