ELECTROMAGNETIC FIELD ENERGY RECYCLING

摘要

A magnetic field energy recycling circuit comprises a capacitor (C1), an inductive device (L1) and a switching circuit (S1, S2, SC), that is sequentially configurable, firstly to direct a discharge current to flow in a first direction from the capacitor and through the inductive device to establish a magnetic field in association with the inductive device; then secondly to direct a current induced in the inductive device during collapse of the magnetic field to flow into the capacitor in a second direction that is opposite the first direction to thereby charge the capacitor. The circuit is connected to a supply of electrical energy (V1) such that current from the supply flows through the capacitor and the inductive device when the switching circuit is configured in the first and/or the second configuration.
