Abstract
In a circuit, switch (1) switches a current from a reference voltage terminal through an inductive element (3). The energy stored in the magnetic field associated with the inductive element when a current is flowing is transferred on interruption of the current either capacitively or inductively to an energy storage element (4). The stored energy is then returned to re-energize the inductive element (3) when the current flow is restored by the switch (1).
