Abstract:Doktorska disertacija obravnava razvoj in izvedbo emulatorja v realnem času za sisteme močnostne elektronike. Emulacija je izvedena in se izvaja na polju prostoprogramirljivih logičnih vezij (FPGA), ki zaradi svoje zgradbe in načina delovanja omogoča hitre izračune sistemov enačb z izrazitim paralelnim značajem. Sistem s takšnim značajem je matematični zapis delovanja sistemov močnostne elektronike v obliki sistema diferencialnih enačb, do katerega pridemo s pomočjo teorije grafov in Kirchhoffovih zakonov. Za zapis splošnega modela se uporabljata pristop z povezovalno matriko, ki opisuje zančno metodo, in pristop z incidenčno matriko, ki opisuje vozliščno metodo. Modulacijski signali, s katerimi vklapljamo polprevodniška stikala v pretvornikih, vplivajo na spreminjanje koeficientov diferencialnih enačb modela. Takšen način omogoča avtomatizacijo modeliranja, saj lahko z njim z ustreznimi vhodi zapišemo poljubno vezje. Emulator je verificiran s simulacijami in z eksperimenti v sočasnem izvajanju z realnima pretvornikoma: usmernik in enofazni DC-AC razsmernik.

Title:FPGA BASED REAL-TIME EMULATION SYSTEM FOR POWER ELECTRONICS CONVERTERS
Abstract:This doctoral thesis deals with an emulation system for Power Electronics Converters (PEC). The emulation of PECs is performed on a Field-Programmable Gate Array (FPGA) capable of hard real-time operation. In order to obtain such a system, the converter operation is described by using a Differential Equations-based model designed with the graph theory. Differential Equations coefficients are changed according to the type of converter and pulse-width modulation (PWM) signals. The tie-set and incidence matrix approach for the converter modelling is performed in order to describe the converter operation in a general way. Such approach enables that any type of PECs can be described appropriately. The emulator is verified with simulations and experimentally by synchronous operation with a real rectifier and DC-AC converter circuits built for these purposes.
Keywords:power electronics, modelling, network theory, emulation, FPGA
