Abstract
Systems and methods of the present disclosure, in accordance with one or more embodiments, include a current source adapted to provides volts*sec at a fixed frequency, a magnetic core adapted to be saturated with energy, and a control winding around the magnetic core. The control winding is adapted to receive current from the current source to saturate the magnetic core. A control circuit is adapted to selectively provide additional volt*sec for at least one half of a cycle of the fixed frequency to the control winding. A second winding around the magnetic core provides a load current to a load through desaturation of energy stored in the magnetic core.

A system comprising:
- a current source providing volts*sec at a fixed frequency;
- a magnetic core adapted to be saturated with energy;
- a control winding around the magnetic core, the control winding adapted to receive current from the current source to saturate the magnetic core;
- a control circuit for selectively providing additional volt*sec for at least one half of a cycle of the fixed frequency to the control winding;
- and
- a second winding around the magnetic core for providing a load current to a load through desaturation of energy stored in the magnetic core.
A method comprising:
- providing volts*sec at a fixed frequency;
- saturating a magnetic core with energy by applying current to a control winding around the magnetic core;
- selectively providing additional volt*sec for at least one half of a cycle of the fixed frequency to the control winding;
- and
- providing a load current to a load through desaturation of energy stored in the magnetic core from a second winding around the magnetic core.
A system comprising:
- means for providing volts*sec at a fixed frequency;
- means for saturating a magnetic core with energy by applying current to a control winding around the magnetic core;
- means for selectively providing additional volt*sec for at least one half of a cycle of the fixed frequency to the control winding;
- and
- means for providing a load current to a load through desaturation of energy stored in the magnetic core from a second winding around the magnetic core.
