碩士 === 大同大學 === 電機工程學系(所) === 102 === A high voltage power supply with continuous adjustable function for corona wind radiating application is proposed in this thesis. First, the digital control scheme is adopted to overcome the problem for difficultly modulating the output voltage for traditional high voltage power supply. Moreover, the implemented single-transformer incorporating voltage multiplier structure and multi-transformers structure are used to compare the system performances. Next, all the mathematical models in the all operating mode are derived to get the corresponding relationship between the control signal and the output voltage. Furthermore, the prototype achieves electrical isolation and cost down by using the primary side control (PSR) technique to conduct the voltage feedback. In addition, the over current protection function is also incorporated into this system. Finally, the power factor corrector (PFC), auxiliary power circuit and high voltage power supply are integrated in the proposed system. Besides, all the simulation and experimental results are very close to the theory predictions.
