Executive Management Team

Ashraf Lotfi, Ph.D.

Chief Executive Officer and Founder

Ashraf is a world renowned leader and expert in power electronics, power management and power technologies. Having been continuously involved in leading teams in research, design and commercial development in the power field for over 25 years, he brings many technical, managerial and leadership qualities to his role.

Prior to founding Enpirion, he led the power management R&D effort at Bell Laboratories as Director of Power Management Research (Lucent/Agere). He formulated a vision for a research effort with the ambitious goal of creating the technology pieces needed to create, for the first time, true power management on a single chip. These efforts combined multiple technology disciplines such as power semiconductor design, RF circuit design, high-speed power topologies, magnetic design and package technology in a highly coordinated development to achieve a commercially viable yet breakthrough technology which enables high performance in a single chip in an economical manner.

He has also served as Department Head, Power Systems Research at Lucent/Agere. In a previous position, his development efforts in power systems applications included high-density dc/dc power modules, planar high density magnetics, custom dc/dc converters, high power rectifiers and battery plants for telecommunications energy supplies. These technologies formed the cornerstone for many product lines that allowed Lucent's (previously AT&T's) Power Systems Division to deliver highly differentiated products in the market place, which resulted in commanding leadership market share and revenues. He also held various engineering and instructor positions at Virginia Tech and Cairo University.

Dr. Lotfi has authored a very large number of publications and white papers that have appeared in leading journals and at specialized meetings in the field of power. He is inventor on over 100 issued and pending U.S. patents, all of which are directly related to power technologies and products.
