Abstract
Embodiments described herein are directed to power switching circuits having a saturable inductor. In one embodiment, a power switching circuit includes a power switch assembly operable to be connected to a power source. The power switch assembly includes a plurality of parallel power switches connected to and receiving current from the power source and a saturable inductor electrically coupled in series with the plurality of parallel power switches.
Claims20
A power switching circuit comprising:
- a power switch assembly operable to be connected to a power source, the power switch assembly comprising:
- a plurality of parallel power switches connected to and receiving current from the power source;
- and
- a saturable inductor electrically coupled in series with the plurality of parallel power switches for reducing a flow of load current over time into the plurality of parallel power switches without contributing inductance to LC resonance of the power switching circuit during load transients.

- a power switch assembly connected to the power source, the power switch assembly comprising:
- a plurality of parallel power switches connected to and receiving current from the power source;
- a saturable inductor electrically coupled in series with the plurality of parallel power switches for reducing a flow of load current over time into the plurality of parallel power switches without contributing inductance to LC resonance of the power switching circuit during load transients, wherein the saturable inductor comprises a core made of a saturating core material which saturates over a time period between about 10 microseconds and about 100 microseconds to an inductance of about 31 nH;
- and
- one or more switching components electrically coupled in series with the saturable inductor such that when the plurality of parallel power switches are turned off, the one or more switching components enable any residual current to flow through to the saturable inductor.
