On behalf of the Organizing Committee, we would like to invite you to the 3rd International Conference on Electric Power Equipment – Switching Technology, which will take place from 25 through 28 October 2015 in Busan, Korea. The ICEPE-ST 2015 is a bi-yearly conference for discussing new inventions and exchanging information and ideas among global researchers from switching technology. The first ICEPE-ST 2011 was held in October 2011 in China and the second was held in October 2013 in Japan. The ICEPE-ST 2015 will offer opportunities to share the most up-to-date scientific discoveries and innovative products. The ultimate objective is to advance our field of switching technology through networking among academia, industries, and all affiliated specialists and building mutual understanding among colleagues from all over the world. Renowned with the long legacy of history and the reputation as one of the world class cities, you will find both the past and the future here in Busan. I hope that you will enjoy the sightseeing of the beautiful beaches, the shopping, and the recreational activities in Busan.
