A method for transferring power between two DC circuits, each circuit being bipolar or connected at the midpoint thereof, involves: coupling the high voltage bus across a pair of inductors, arranged in parallel; coupling the low voltage bus across the pair of inductors; coupling the high voltage bus, the low voltage bus and the inductors by active switches and diodes, to provide for: (i) a storage configuration, wherein energy is transferred from one of the buses and stored in the inductors; and (ii) a release configuration, wherein energy is released from the inductors and transferred to the other of the buses.

Method for power transfer between DC circuits

The present invention provides a series of DC-DC converter circuit designs, and DC-DC converters based on such circuit design, that provide high input-to-output voltage conversion. The converters include a resonant tank and a means for interrupting the tank current to produce a near zero-loss 'hold' state wherein zero current and/or zero voltage switching is provided, while providing control over the amount of power transfer. A resonant DC-DC converter for high voltage step-up ratio in accordance with the circuit design includes: (a) a low voltage DC-AC converter, (b) a resonant tank, (c) a high voltage AC-DC converter, (d) a (i) common ground on an input and an output without use of a transformer and/or (ii) a single high voltage controllable switch within the resonant tank.
