Design and Implementation of an Electronic Ballast with Intrinsic Power Regulation Majid Dehghani deh maj@yahoo com October 2009 Department of Electrical and Computer Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Seid Mortaza Saghaiannejad Supervisor saghaian@cc iut ac ir Hamid Reza Karshenas Advisor karshen@cc iut ac ir Seid Mahmoud Modarres Hashemi Department Graduate Coordinator Department of Electrical and computer Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Abstract High frequency electronic ballasts for high intensity discharge HID lamps have significant advantages in compare with magnetic ballasts However the conventional electronic ballasts are not used extensively due to their low reliability and high price This dissertation develops an electronic ballast and a dimmable electronic ballast which provides intrinsic power regulation during the entire lamp life without using a closed loop control system The ballast design is based on improving six quality indices reliability lamp lifetime luminous flux regulation energy consumption input current quality and cost A mathematical model for the ballast is developed and used for the ballasts design and analysis A design procedure is presented to design the ballasts To improve technical specifications practical and standard constrains are considered in the ballasts design An electronic ballast and a dimmable electronic ballast for 250 W HPS lamp are designed The theoretical analyses are validated by the experimental tests of laboratory scale electronic ballasts The experimental results demonstrate that the design ballasts provide intrinsically a regulated power during the entire lamp life Keywords Electronic ballast Dimmable electronic ballast High pressure sodium lamp Power regulation design Optimization Introduction The HID lamps are extensively used for public lighting systems because of their long lifetime and high light efficiency The HPS lamp has the highest light efficiency in compare with the other HID lamps Hence it is the most favorite HID lamp for public lighting systems The HPS lamp has a negative characteristic impedance Thus it is interfaced to the source through a ballast which limits the lamp current 1 Electronic ballasts and dimmable electronic ballasts have significant advantages in compare with magnetic ballasts The advantages include higher efficiency and power
