| 20100202166 | ENERGY SAVING LUMENS SETTABLE DEVICE FOR FLUORESCENT LAMPS - A circuit to supply an AC voltage to a fluorescent lamp load from an AC supply converts the supply to DC, boosts the voltage in a converter and then drives an inverter from the smoothed boosted voltage in such a manner that the inverter will not start if the load is too low and the inverter frequency is almost constant. The power factor of the circuit is maintaining very close to unity. | 08-12-2010 |
| 20100072960 | SWITCHING TECHNIQUE FOR EFFICIENT ELECTRICAL POWER UTILIZATION - An active phase angle correction circuit which corrects the phase angle between voltage and current in an AC supply varies the capacitive loading of the AC mains to reduce the phase angle to near zero by detecting the phase angle, reactively and resistively loading the AC mains in steps until the phase angle is at a desired level close to zero, and then maintaining or incrementally adjusting the loading. The applied loading may be continuously switched in and out at a rate much greater than the mains supply frequency. | 03-25-2010 |
