Design and Simulation of Power conversion using open source tools

By Prof. L Umanand   |   IISc Bangalore
This is a simulation oriented course. There are many power conversion topologies that are used in several applications like power supplies and power converters. These will be studied through simulation. This course emphasises learning and understanding converter topologies through the aid of open sources tools like octave, gEDA and ngSpice. The course starts with a discussion on simulation tools and their installation. Both NgSpice and Octave environments are used to simulate circuit based and model based systems. PV cells, rectifiers, switched mode non-isolated and isolated converters are studied through simulation. Discussions on various topologies are strengthened with the aid of simulation demonstrations.

INTENDED AUDIENCE : 3rd or 4th year UG, 1st year masters and research students
UG/PG course, industry people can also register.
PRE-REQUISITES   : Basic electric circuits
