摘要：A switching apparatus allows coupled coils to be dynamically switched in or out

of a circuit using small control currents. The apparatus includes at least one latchingcircuit, one or more control circuits and diodes. The latching circuit may have two bipolartransistors connected in a transistor latch configuration with at least two diodes, suchthat at least one diode may be connected in series with a base of the each bipolartransistor. The control circuits may be connected to the latch circuit for operating thebipolar transistors. The diodes may be connected in the circuit for protecting the latchingand control circuits from being exposed to high voltages and currents during the turn-offor turn-on of the inductor coils. This allows overall efficiency levels to be maintainedwhile changing the inductance of the circuit as per requirements. The circuits may be usedin switch mode power supplies (SMPS).
