20.500.12556/DKUM-71100 Mikrovalovna stimulacija pečniške komore s frekvenčnim preletom na osnovi polprevodniške tehnologije Microwave stimulation of heating cavity with frequency sweep based on solid state technology Magistrsko delo opisuje razvoj sistema za mikrovalovno stimulacijo s frekvenčnim preletom na osnovi polprevodniške tehnologije. Cilj razvitega sistema je doseganje visoke storilnosti ob homogenem segrevanju bremen. Predstavljen sistem temelji na generiranju in dovajanju visokofrekvenčnega signala visoke moči v pečniški prostor, pri čemer regulacijski sistem s pomočjo preciznih visokofrekvenčnih detektorjev spremlja količino reflektirane in posredovane energije na posameznih frekvencah. Za doseganje visoke stopnje storilnosti in homogenosti segrevanja skrbi strojno pospešen algoritem, ki v stvarnem času, na podlagi pridobljenih informacij o razmerah v pečniškem prostoru, prilagaja izhodno moč in preoblikuje način frekvenčnega preleta za optimalno izrabo razpoložljivega časa v frekvencah z visoko stopnjo absorpcije generiranih oscilacij. Verifikacija delovanja je bila izvedena na realnih bremenih. Stimulacijski scenariji pa so bili zasnovani za merjenje storilnosti in homogenosti segrevanja. This master thesis describes the development of a microwave stimulation system with frequency sweep based on the solid state technology. The system was developed with the purpose to achieve high efficiency and heating uniformity. The described working concept is based on generating and delivering a high frequency and high power signal to the heating cavity, while performing the measurements of the reflected and forward power using a high precision RF detector. To achieve the high efficiency and heating uniformity the development of stimulating algorithm was inevitable. A real time processing algorithm performs the adjustments of the output power and reshapes the frequency sweep control signal based on the coupled values of the reflected and the forward power. Reshaping the control signal results in optimizing the use of available time at frequencies with higher absorptions capabilities. Verification tests of the working system were performed on real loads. Testing scenarios were designed to measure the efficiency and the heating uniformity. mikrovalovna stimulacija polprevodniška tehnologija homogenost segrevanja frekvenčni prelet visokofrekvenčni detektor microwave stimulation solid state technology heating uniformity frequency sweep RF detector true true false M.
