Patent ID: 7330055

Claim:
A power control circuit comprising: (a) a first optocoupler/logic stage, said first optocoupler/logic stage receiving a first input signal and outputting a first pair of complimentary voltage waveforms; (b) a second optocoupler/logic stage, said second optocoupler/logic stage receiving a second input signal and outputting a second pair of complimentary voltage waveforms; (c) a first voltage-to-current driver stage, said first optocoupler/logic stage electrically coupled to said first voltage-to-current driver stage, said first pair of complimentary voltage waveforms driving to a first pair of JFET switches within said first voltage-to-current driver stage; (d) a second voltage-to-current driver stage, said second optocoupler/logic stage electrically coupled to said second voltage-to-current driver stage, said second pair of complimentary voltage waveforms driving to a second pair of JFET switches within said second voltage-to-current driver stage; and (e) a halfbridge stage, said first voltage-to-current driver stage and said second voltage-to-current driver stage electrically coupled to said halfbridge stage, said first pair of JFET switches controlling a first BJT switch within said halfbridge stage, said second pair of JFET switches controlling a second BJT switch within said halfbridge stage, said first BJT switch and said second BJT switch functionally sequenced to produce a high-power output signal.
