Endüstriye yönelik uygulamalar için bütünüyle sic güç mosfet teknolojisine dayalı üç faz PWM doğrultucu

In this thesis work, a three phase PWM Rectifier for industry applications will be designed by using SiC Power MOSFETs and its laboratory prototype will then be implemented. The topology of the PWM rectifier is the three phase full bridge topology to convert three phase 400 V AC line-to-line voltage to desirable voltage levels between 500V and 1000V. The PWM Rectifier has the capability of permitting the flow of active power in both directions. The new technology SiC Power MOSFETs can operate at higher frequencies than IGBTs which provide higher efficiency because of lower switching losses and comparable conduction losses. Furthermore, operation at higher frequencies also provides us much lower acoustic noise levels and less harmonic distortion in line current waveforms during the operation of the rectifier. The theoretical results will be verified by experimental work.Thesis (M.S.) -- Graduate School of Natural and Applied Sciences. Electrical and Electronics Engineering
