Power Factor Correction Using 8051
ACKNOWLEDGEMENT It gives us an immense pleasure to write an acknowledgement to this project report, a contribution of all people who helped us realize it. We take this opportunity to express our respectful regards to our beloved principal Dr.N.C.Hiremath for permitting us to do this project. We express our deep sense of gratitude and appreciation to our beloved HOD Prof.S.B.Patil for this enthusiastic inspiration and amicable in all phases of our project. With due respect we would like to express my sincere thanks to our project guides Prof.H.R.Zinage and Prof.S.M.Mukare for their sterling effort and timely giddiness, their patience in solving our doubts which kept cropping up in due course of our project needs special credits. We heartily thank our coordinator Prof.O.B.Heddurshetti for his encouragement and support towards our academic and project work. Our sincere thanks to all those people who have contributed to project in every step. By Shruthi S. Kurhade Laxmi S. Chavan Vanishree C. Hiremath Naveen V. Nula
