Claims18
An electronic power control system comprising:
- a single conductor for supplying circuit power, said conductor also providing a command voltage, said conductor coupled to a diode, a resistive element and a voltage regulator which, in the presence of an input current from said conductor, induces an output to power a drive, a circuit of said drive capable of issuing a non-mid-state, fast rise and fall time voltage output to a power semiconductor;
- wherein user supplied input voltage allows a semi-conductor to release the input of the drive circuit, thereby allowing for filtered voltage change at the input from a low state to a threshold state, at which time fast rise-time voltage is delivered to said power semiconductor and to series-coupled capacitive and resistive elements which feed back to the input to lock the input above or below a threshold voltage;
- and
- wherein the output drives said semi-conductor through a capacitor pumping circuit to induce a negative voltage bias in the semi-conductor input.

A controller comprising:
- a single conductor for supplying circuit power, said conductor also providing a command voltage, said conductor coupled to a diode, a resistive element and a voltage regulator which, in the presence of an input current from said conductor, induces an output to power a drive, said drive capable of issuing a non-mid-state, fast rise and fall time voltage output to a power semiconductor;

- wherein the feedback supplied input voltage induces clamping of the drive output upon reaching a low voltage threshold state;
- wherein small filtered voltage-level changes applied to the input of said drive induce adaptive dither modulation (ADM)-regulation behavior to maintain a user-selectable criteria;
- and
- wherein the drive output drives said power semi-conductor through a capacitor pumping circuit to induce a negative voltage bias in the power semi-conductor input.
