Two-state, bilateral, single-pole, double-throw, half-bridge power-switching apparatus and power supply means for such electronic power switching apparatus
First Claim
1. A two-state switching apparatus adapted to drive a load comprising a first FET;
- single-wire connector means for connecting said switching apparatus to source means for switching signals, said single-wire connector means being connected to the gate of said first FET;
a second FET, said second FET having its gate connected to the drain of said first FET, and its source connected to the drain of said first FET through means for preventing cross-current from said first FET to said second FET and for permitting the gate voltage on said second FET to be raised sufficiently high to turn on said second FET; and
means for delivering on and off signals to said second FET, and for holding said second FET on or off in response to switching signals having a duty factor in the range of 0% to 100%.

Abstract
Two-state, bilateral, single-pole, double-throw, half-bridge power-switching apparatus capable of high speed, high current switching over a duty factor range of zero percent to 100% includes a single-wire connector to a source of switching signals, a first FET whose gate is connected to the single-wire connector, and a second FET having its gate connected to the drain of the first FET and its source connected to the drain of the first FET through a device for preventing, in part, cross-current from the first FET to the second FET and for permitting the gate voltage on the second FET to be raised sufficiently high to turn on the second FET. The apparatus also includes a system for delivering on/off signals to the second FET and for holding the second FET on or off in response to switching signals having a duty factor in the range of zero percent to 100%.
