This book contains the best papers of the International Conference on Advances in Power Electronics and Instrumentation Engineering, PEIE 2010, organized by the Association of Computer Electronics and Electrical Engineers (ACEEE), during September 7-9, 2010 in Kochi, Kerala, India. PEIE is an international conference integrating two major areas of electrical en- neering - power electronics and instrumentation. Thus this conference reflects a c- tinuing effort to increase the dissemination of recent research results among prof- sionals who work in the areas of power electronics, instrumentation and electrical engineering The program of this joint conference included several outstanding keynote lectures presented by internationally renowned distinguished researchers who are experts in the various PEIE areas. Their keynote speeches have contributed to heightening the ov- all quality of the program and significance of the theme of the conference. I hope that you will find this collection of the best PEIE 2010 papers an excellent source of inspiration as well as a helpful reference for research in the aforementioned areas. Organizing a conference like this one is not possible without the assistance and continuous support of many people and institutions.
