Abstract

See full text

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.
