A power control circuit is presented. The circuit includes a pair of parallel optocoupler/logic stages and a pair of parallel voltage-to-current driver stages electrically coupled to a halfbridge stage in the order described. An input signal is communicated to the optocoupler/logic stage and processed therein to produce two distinctly separate but complimentary waveforms. Complimentary waveforms are communicated to the voltage-to-current driver stage to drive a paired arrangement of JFET switches. Thereafter, the JFET switches communicate with the halfbridge stage to control function of BJT switches. BJT switches are sequenced to produce a high power output. The present invention has immediate applicability to power conditioning, control, and distribution systems, as well as other applications which include or rely on silicon power transistors.
