  • Solid state power control apparatus
    Patent number: 3958131
    Abstract: A solid state power controller adapted for use with a single or multiple phase A.C. power source employs, for each phase, oppositely poled directional transistor switches connected in parallel with a load, and parallel oppositely poled directional transistor switches serially connecting the load and a line source phase.Control circuitry is provided for rendering the serial transistor switches selectively operative in a chopping, pulse modulated mode which is variable to effect power control. The load shunting directional switches are alternately enabled responsive to the instantaneous line voltage polarity for transient suppression.
