20090201620 | ELECTROMAGNETIC FIELD ENERGY RECYCLING - An electromagnetic field energy recycling circuit recovers energy from collapsing magnetic fields, stores recovered energy as charge on a capacitance, and subsequently re-uses stored recovered energy to establish a magnetic field. Capacitance and inductance are sequentially connected in various configurations to recycle the energy by a discontinuous resonant energy transfer. In a magnetizing configuration, a magnetic field is established by transfer of energy from a capacitance to an inductance. In a recovery configuration, a capacitance is charged with energy recovered from the inductance on collapse of the magnetic field. In a third configuration, recovered energy stored by the capacitance is held until required for establishing a magnetic field. During magnetizing, the capacitance voltage drops by at least 50%: preferably to zero. During recovery, current flowing in the inductance falls to zero. The circuit drives electromagnetic devices, e.g., electric motors, generators, transformers, solenoids, induction heating coils and inductive power transfer windings. | 08-13-2009 |
