SUMMARY:IEEE Durham Region Subsection Speaker series
DESCRIPTION:Talk 1:  In this talk\, the operation of DC-DC converters\, which work by exchanging energy between storage elements due to the action of switching semiconductors are explored. The storage elements (mainly inductors and capacitors) are also called passive components. The size of the converters is highly influenced by the size of inductors and capacitors which is at the same time influenced by the power dissipation and the stored energy. It is desirable to design compact converters. However\, reducing this energy cannot be done arbitrarily due to the constraints imposed by switching ripple specifications\, and reducing the power rating cannot be done due to safety. Various topologies that have been designed with reduced stored energy\, examining their advantages and the trade-offs involved will be highlighted. The discussion will highlight innovative approaches to achieving efficiency and compactness in converter design.  Talk 2:  Designing compensators for control models in the αβ0 reference frame for tracking sinusoidal functions of time is not a straightforward task. Alternatively\, a control scheme in dq reference frame offers the possibility to track dc control signals. It also allows simpler design of compensators. This talk covers a control scheme in the dq reference frame integrated to a modulator and voltage balancing algorithm for Hexverter-based systems functioning as an intertie. It can be considered as an extension of the control model developed for the two-level voltage source inverter. By doing so\, an independent regulation of the Hexverter’s active and reactive power flows can be realized. The control system is validated using PSCAD/EMTDC computer simulations.
