20080198637 | Multilevel AC/DC converter for traction applications - The present disclosure is concerned with a power supply system for railway traction applications including a multilevel AC/DC converter. The converter comprises a plurality of series-connected single-stage cycloconverters or direct AC frequency converters connected between an AC supply line and a traction transformer. The transformer is operable at a transformer nominal frequency below 3 kHz and above the AC line frequency. On the secondary side of the transformer, more than one parallel-connected secondary converter are provided and connected to a DC link. In case of failure of one of the secondary converters, the multilevel AC/DC converter may continue to operate with reduced power delivered by the remaining operating levels. | 08-21-2008 |

20120134148 | LED LIGHTING WITH INCANDESCENT LAMP COLOR TEMPERATURE BEHAVIOR - In a lighting device, sets of LEDs are employed using the natural characteristics of the LEDs to resemble incandescent lamp behavior when dimmed, thereby obviating the need for sophisticated controls. A first set of at least one LED produces light with a first color temperature, and a second set of at least one LED produces light with a second color temperature. The first set and the second set are connected in series, or the first set and the second set are connected in parallel, possibly with a resistive element in series with the first or the second set. The first set and the second set differ in temperature behavior, or have different dynamic electrical resistance. The light device produces light with a color point parallel and close to a blackbody curve. | 05-31-2012 |
