Abstract Title : Switching Loss Analysis of Different Power Semiconductors
|
Abstract :
FREEDM (Future Renewable Electric Energy Delivery and Management) is a brand-new smart micro-grid system. The key networking equipments of FREEDM are SSFID and SST which include different kinds of power semiconductors. Thus, the switching loss of power semiconductors should be taken into consideration in order to advance the efficiency of SST and SSFID. In this project, the switching loss of different power semiconductors in Boost converter circuit was analyzed and compared through simulations of Pspice. Switching loss was also calculated based on datasheets of different semiconductors. Meanwhile the data of switching loss was measured through oscilloscope in real Boost converter circuit. Combining all of the results of simulations of Pspice, calculations based on datasheets and experiments of real circuits, it proves that different power semiconductors have different switching losses and they should be chosen according to the actual situation. The results are meaningful because low switching loss helps save energy and update efficiency.
