The invention creates a pattern-based conversion model to identify ad hoc numerical phrases to increase the accuracy of simplified to traditional Chinese character conversions. The fact that one simplified character can correspond to several traditional Chinese characters of different meanings under.....

During the turn-on and turn-off switching processes, power converters have to withstand high voltage and current, leading to high switching losses and stresses. The invention is a passive lossless snubber cell with minimum stress and wide soft-switching range. The energy reset / recirculation proces.....

Existing methods for multi-string applications require many windings in the isolation transformers because each converter output needs one winding. This invention, a dimmable LED driver, can reduce the number of windings. It also possesses a two-secondary-winding structure to generate several source.....
