U radu je projektiran i realiziran visokofrekvencijski generator hladne plazme. Generator ima akumulatorsko napajanje s integriranim punjačem i mjeračem stanja napunjenosti. Sklopovi napajanja odvojeno napajaju kontrolne sklopove generatora te energetski dio za generiranje visokog napona. Pomoću visokonaponskog transformatora se realizira izmjenični visoki napon frekvencije 50 kHz potreban za stvaranje hladne plazme. Kod projektiranja sustava posebno se obratila pozornost na minimizaciju potrošnje energije i smanjena fizičkih gabarita elektroničkih sklopova. Realiziran je probni sustav na tiskanoj pločici, testirana mu je funkcionalnost te pouzdanost rada za vrijeme generiranja hladne plazme. The theme of this graduate thesis was designing and realization of a high-frequency cold plasma generator. Generator is powered by battery with an integrated charger and charge gage. Power supply assemblies separately power generator control circuits and power section for generating high voltage. With the use of a high-voltage transformer we can realize alternating high voltage that has frequency of a 50 kHz that is needed to produce cold plasma. When designing the system, special attention has been paid to minimizing energy consumption and reducing physical dimensions of electronic circuits. A test system was implemented on the printed circuit board. The functionality and reliability of the circuit board were tested during the process of generating cold plasma. |
