dc.description.abstract Power electronics has been gaining widespread popularity because of the development that have taken place in areas like power semiconductor devices, micro-electronics, control and power apparatus in the last five decades. Power electronic systems are complex, besides the fact that a number of new circuit topologies have come into being. Coupled to this is a widespread use of non-linear loads that has given rise to new issues such as power quality and voltage stability. In this context, a flexible approach to the understanding of power electronic systems is needed that can be used both for design and education with a possibility for rapid learning and prototyping. A modular approach to real-time implementation of power electronic circuits using the Texas Instrument DSP controller TMS32OF240 is proposed in this thesis. Besides offering flexibility to a designer/researcher, this approach can also be used to impart a modern power electronics education. Real-time hardware and software constructs for a number of power electronic circuits have been developed that can be quickly integrated to have the desired power electronic topology. A number of topologies can be quickly tested by choosing the appropriate hardware and software modules. Moreover, as the power electronic converter can be controlled in real-time from a computer, the designer can quickly tune the circuit to one's specific needs. The concept has been proved to cut down turn around time and development cost of building such a power electronics laboratory. Also proposed in this thesis is an object-oriented simulation approach for modeling and designing power electronic systems using the simulator DYMOLA. This software approach also provides for a virtual state-of-the-art power electronics laboratory where a circuit of any complexity can be quickly modeled simulated and analyzed. As DYMOLA does not have an inbuilt measurement and analysis tool, two user-created tools have been developed. The first is a MATLAB based off-line tool but modeled with DYMOLA. This tool is developed by exploiting the ability of DYMOLA to interface with external simulators. An on-line measurement tool written in DYMOLA has also been developed. The object-oriented measurement tools in DYMOLA also make graphical modeling of power electronic systems with measurement templates a reality.
