摘要： Particle traps are often used to reduce particulate emissions from internal combustion engines to acceptable levels. In order to maintain the particulate traps, they must be periodically regenerated in order to burn off the trapped particles. Strategies for efficiently regenerating the particle traps have been elusive. The present invention separates the exhaust flow into several flow paths. During regeneration, the flow paths are sequentially partially closed, and the particle traps in each of the flow paths are individually regenerated using electrically conductive filter elements. The present invention can be used to effectively filter particles from any combustion process, especially exhaust from internal combustion engines. The particle trap assembly achieves a relatively low pressure loss and efficient regeneration by supplying an oxidizer via a small cross-flow passage.

摘要： A converter for an LED driver for an LED light source. The converter has a flyback transformer. The primary receives a rectified AC voltage. A switching transistor is coupled in series with the primary. A controller controls the switching transistor on and off to generate a bus voltage across the secondary and a center tap voltage at a center tap of the secondary. The controller is powered by a first low-voltage DC voltage. A first power supply receives the center tap voltage and generates a second low-voltage DC voltage when the center tap voltage is above a cutover voltage. A second power supply has an output coupled to the first power supply output. The second power supply receives the bus voltage and generates the second DC voltage when the center tap voltage is below the cutover voltage.
