摘要: A class of switching power supplies that use a resonant isolation stage (typically LLC) fed directly or via a diode bridge from the line. Extension of the range of available gain values over frequency without material loss of efficiency is facilitated by usage of additional resonant elements. This capability allows the devices to provide narrow-range inputs to secondary-processing circuits, with the ability to achieve power factor correction if required. The conversion architecture is also compatible with optimal usage of energy storage elements suitable for use with switching power supplies.

摘要: The present application relates to magnetic components employed in switching power supplies. The application provides a gapped magnetic core (20) construction in which the gap is distributed by placing gaps between the legs (23) of the core and the top and bottom sections (21, 22). The application also provides a bobbin construction having a reduced footprint for inductor and transformers.

摘要: The present application is directed to drive arrangement for semiconductor switches and in particular to a method of driving the gate of a switch with pulses corresponding to turn-on and turn-off commands through separate turn-on and turn-off transformers. The application provides a fail safe reset feature, a more efficient turn-on circuit and an energy recovery circuit for recovering energy from the gate upon turn-off. The application also provides a novel arrangement for assembling multiple pulse transformers on a circuit board.
