Transformer thermal and loss of life models

  In this paper, transformer thermal and loss of life models was studied. Based on the thermal model adopted by International Standards, small improvements to increase model accuracy are presented and a comparative study of resulted accuracy under different load and ambient temperature profiles was performed. Key words: Transformer thermal, loss of life models, estimate thermal parameters.

Implementation of DSP algorithms on reconfigurable embedded platform

Field programmable PLD’s are becoming a standard in hardware technologies, as application demands have out placed the conventional processor's ability to deliver. The right combination of price, performance, ease-of use, along with significant power savings, can be achieved by using a Field Programmable Gate Array (FPGA). The versatility of these devices with the EDA tools such as Quartus, ISE,...
