Latest Patents

One of Orman's latest patents is the Dual-mode power converter. This invention provides an efficient off-line rectified, high-power, AC-to-DC power supply. It achieves high power factor and minimal circuit size, cost, and complexity by combining switchmode power converter operation with conduction-mode operation. The switchmode power converter is controlled to convert only a fraction of the output power, allowing peak power to be efficiently conducted directly from an AC line to a DC output without requiring the operation of the switchmode power converter. This control method results in high efficiency while maintaining a high-power factor with optimally sized, cost-effective switchmode power converter electronics. The invention includes a complete, self-contained system featuring a soft-start, full-wave bridge.

Another significant patent is the Apparatus for providing controlled mechanical braking torque. This invention employs direct field drive incorporating an AC alternator plus a current regulator to electrically generate mechanical braking torque. The stator windings of the alternator are directly coupled to the field winding via a full wave rectifier and the current regulator. This invention simplifies electrical circuitry for generating braking torque, provides a wide dynamic range of torque generation, limits voltages and currents to manageable levels, and reduces mechanical drive train requirements. It produces a constant power mechanical load from essentially 0 to over 1,000 watts from an alternator typically used for automotive applications.
