Acácio Manuel Raposo Amaral
Acácio Amaral was born in Luso, Angola, in 1974. He received the Electrical Engineering diploma, the MSc degree and the Dr. Eng. degree all from the University of Coimbra, Coimbra, Portugal, in 1998, 2005 and 2011 respectively. Since 1998, he has been with the Polytechnic Institute of Coimbra, where he is currently an Assistant Reader in the Department of Informatics and Systems. His research activities include fault diagnosis and design of switch-mode power supplies, with emphasis on the consequences of aging of electrolytic capacitors, as well as the development of solutions to this problem.
