Inductive circuit arrangements |
摘要 |
A switched coil arrangement is connected in a bridge configuration of four switches S1, S2, S3 and S4 which are each shunted by diodes D1, D2, D3 and D4 so that current can flow in either direction through a coil L depending on the setting of the switches. A capacitor C is connected across the bridge through a switch S5 to receive the inductive energy stored in coil L on breaking the current flow path through the coil. The electrostatic energy stored in capacitor C can then be used to supply current through the coil in the reverse direction either immediately or after a time delay. Coil L may be a superconductive coil. Losses in the circuit can be made up by a trickle charge of capacitor C from a separate supply V2.
