ABSTRACT:
A bidirectional solid state power switch module includes two solid state switches, each having an antiparallel diode, connected in common electrode configuration by a juncture therebetween. A pair of unilaterally conductive paths, each poled to conduct in a direction to maintain current through the switch module which is cut off by turning off the adjacent switch, each connected to an extreme end of the switch module, the other end of said first unilaterally conductive paths being connected together to a first side of a capacitor, the opposite end of the capacitor being connected through a unilaterally conductive path to the juncture between the two switches, said second unilaterally conductive path being poled to conduct current that passes through either of said first paths and said capacitor. Upon cutoff of one of said switches, current flows through one of said first unilaterally conductive paths, said capacitor, and said second unilaterally conductive path and through the antidiode of the other of said switches. Since the voltage across the capacitor is always opposite to the conductivity of the unilaterally conductive paths with which it is in series, the capacitor of one such clamp can be connected in parallel with the capacitor of other clamps, and the voltage thereacross regulated by a single regulator, such as a resistor fed through a solid state switch controlled by a threshold detector.
