Circuit system and method for coupling a circuit module to or for decoupling same from a main bus

摘要

A circuit system comprises a main bus, a circuit module connected to a sub-bus, a saturable magnetic switch connected between the sub-bus and the main bus, wherein the saturable magnetic switch has a first inductance in a first saturation state and a second inductance in a second saturation state, the first inductance being lower than the second inductance, means for placing the magnetic switch in the first saturation state so coupling the sub-bus to the main bus, or for placing saturable magnetic switch in the second saturation state for decoupling the sub-bus from the main bus.
