Abstract
An electromagnetic field energy recycling circuit recovers energy from a collapsing magnetic field, stores the recovered energy as charge on a capacitance, and subsequently re-uses the stored recovered energy to establish a magnetic field. Capacitance (Cl) and inductance (Ll, L2) are sequentially connected in various circuit configurations to recycle the energy by a dis-continuous resonant energy transfer. In a magnetising configuration, a magnetic field is established by transfer of energy stored on a capacitance to an inductance (Ll). In a field energy recovery configuration, a capacitance is charged with energy recovered from the inductance on collapse of the magnetic field. In a third configuration, the recovered energy stored by the capacitance is held until required for establishing a magnetic field. During the magnetising configuration, voltage on the capacitance drops by at least 50% and preferably to zero. During the recovery configuration, current flowing in the inductance falls to zero. The circuit can be used to drive electromagnetic devices, eg electric motors, generators, transformers, solenoids, induction heating coils and inductive power transfer windings.
