Design Example: Magnetic Pulse CompressionSATURABLE REACTORSSaturable reactors utilize the large change between unsaturated and saturated permeabilities of theircores to delay current for a preset period of time. Similarly, once saturated in the forward direction, theyact as a diode temporarily blocking current in the reverse direction. (see figure, below)

MAGNETIC SWITCH PROTECTION (MSP)MSP devices made with Metglas®cores have dramatically enhanced the reliability and overall lifetime ofpulse power systems. By using a saturable reactor in series with either a semiconductor or thyratronswitch, the circuit designer can reduce losses in the switch and extend its life. The saturable reactor isdesigned to hold-off current until the switch becomes fully conductive (see figure, right).

Higher di/dt's to the load are safely achieved by waiting forfull conductivity in semiconductor switches. The diode-like characteristic of a saturated reactor providestime for switch recovery.
