Hassan Moghbelli received his B.S. in electrical engineering from Iran University of Science and Technology (IUST) in 1973, his M.S. in electrical engineering from Oklahoma State University in 1978, and his Ph.D. in electrical engineering with specialization in electrical drives and power electronics from University of Missouri, Columbia (UMC), in 1989. Moghbelli was an instructor at Isfahan University of Technology (IUT) from 1978-1984, an Assistant Professor at Purdue University, Calumet, (PUC) from 1989-1993, and an associate professor in IUT and IUST from 1989-2002. He has done several projects in the area of electrical drives, power electronics, and hybrid electric vehicles. He served as the Head of the School of Railway Engineering at IUST from 2000-2002. He served as a consultant at Northern Indiana Commuter Transportation District from 1991-1993 and at Isfahan and Tehran Regional Metro Companies from 1993-2002. He has directed several projects in the areas of electric vehicles and hybrid electric vehicles. He also was a Research Associate in the Advanced Vehicle Systems Research Program in the Department of Electrical Engineering at Texas A&M University from 2002 to 2004. Furthermore, he successfully implemented the Hybrid Electric Vehicles on a Saypa mini bus, which was funded by Ministry of Industry in Iran. He was a Senior Lecturer in the Math Department at TAMU during 2004-2006. He joined the Math and Science Department at Texas A&M, Qatar, in Jan. of 2007, and he is working on NPRP2 research project for Qatar Foundation. His research interests are mainly the control, electric drive train, power electronics, hybrid electric vehicles, CNG vehicles, alternative energy, and power systems. He has published more than 95 scientific papers in these areas. He is a member of SAE, ASME, and IEEE.

Design and Implementation of a Low-Cost Photovoltaic Traffic Light Signal System A. Halvaei Niasar Hassan Moghbelli Department of Electrical Engineering Department of Mathematics University of Kashan Texas A&M University Kashan, P.O.Box: 87317-51167, Iran College Station, TX 77843-3368, USA Abstract- Power failures in roads and crosses cause difficulties due to non-availability oftraffic signal lights. Application of solar energy has been increased to power-up the trafficsignal lights all over the world recently. The proposes of this paper is the use of solar energyin powering traffic signal systems for rural areas with no power grid. A photovoltaic systemis used to capture the energy. The implemented system is simple, low-cost with free-maintenance. The nominal output voltage of the employed solar cell is 12 volts. Capturedsolar energy is saved into a 12 volts lead-acid battery. Instead of dc-dc converters, a circuitincluding IC regulator is used to control the flow of charge through the battery. Timing oftraffic light is carried out via AVR microcontroller. Experimental results for different anglesof radiation at different times of the day is shown in this paper. Keywords-solar cell, traffic signal light, photovoltaic, lead-acid battery, voltageregulation, microcontroller.
