Electro-magnetic flux valve

An apparatus, comprising:

• a magnet surrounded by a ferromagnetic shunt core;
• at least two embedded flux control element sections within the shunt core such that when electrically energized a reluctance of the shunt core increases to a point of magnetic saturation;
• and
• a boost converter drive circuit configured to use an input power switch which isolates the boost converter circuit from a power source during a boost or a recovery phase of operation.

An apparatus, comprising:

• a magnet surrounded by a ferromagnetic shunt core;
• at least two embedded flux control element sections within the shunt core such that when electrically energized a reluctance of the shunt core increases to a point of magnetic saturation;
• and
• a boost converter drive circuit configured to use a passively charged bootstrap capacitor circuit at an input, wherein the passively charged bootstrap capacitor circuit is configured as a clamper to establish a boost voltage threshold during a recovery cycle.
