U.S. Patent Office - Notice of Publication of Application for the "High Efficiency All-Electric Vehicle Propulsion System"
An all-electric vehicle propulsion system using a readily available high frequency AC Motor such as a 3-phase 400 Hz motor. A step-down gearbox increases torque and power thus decreasing the need for a high-power motor. Also, with the controllers of the
invention, readily available, inexpensive batteries can be used as a primary source of energy. An efficient C&A-DC/DC step-up converter to power a high-efficiency motor driver can force the AC-motor windings circulate current in a resonance mode at around 220 volts.

4000V Super-Fast SPDT Switches
NanoSeconds rise/fall time, 4000V push-pull switch. This switch belongs to the family of push-pull switches consists of two alternately controlled
solid-state switches, which in turn are made up to a large number of high-speed MOSFETs
isolated each other connected in series. The rise and fall times at the switch output are
virtually the same and that allow generating an extremely precise, high-voltage, true

Fuzzy-logic, noise-free, f-SPDT Solid-State Drivers
A unique feature of an f-SPDT driver is a fuzzy- logic control and power source for the
internal logic and drivers. The control input designed for the maximum application flexibility and
simplicity in interfacing. It is a high impedance input and any 5V CMOS logic can be used to control
it. The best result can be obtained with tri-state output logic, like bus-driver IC chips or CPUs. The
control input has three defined levels, as that can be seen on the figure, below: 0-1.7V, 1.9-3.2V, and
3.4-5V. That voltage variation allows targeting control any one of terminals or turn “OFF” the driver
(terminals) all together...

Full-Bridge Drivers (H-Switch) for DC Motors
EDR’s H-driver family of drivers provides significant competitive advantage in the power
driver market. An internal precision timer controls a “dead” time between the CW and CCW and
provides true break-before-make commutation that allows driver a high-speed solenoid and not
to worry about a shoot-through current. The enable input is a dual function control. It disables
both outputs (terminals) and cuts external power consumption to the minimum (stand-by)...
