National Cheng Kung University LED driver design won the competition in two future global energy Awards

Taiwan National Cheng Kung University, "the design of high efficiency, high efficiency, adjustable brightness light emitting diode (LED) driver circuit" won 2 awards in the global energy competition.

Cheng said that the global energy competition held every 2 years in the next 1 years, in September last year before the opening of the global university proposal registration. Cheng was born in March this year to participate in the semi-finals, from 30 to July 26th in Hangzhou, Zhejiang University in the finals, a total of 9 college teams into the finals.

A professor from the main motor of beam lead, Chen Jianfu's team, with "high efficient life can adjust the brightness of the wireless light emitting diode (LED) driver circuit design", won the best engineering achievement award and the best creative design award 2 awards.

Responsible person said, this design with high efficiency flyback converter can reduce the low frequency ripple cancellation LED low frequency ripple current, suitable for different global voltage input, and can provide a stable current output, with simple structure, low cost, high efficiency and high life characteristics, to obtain the favor for prizes.
