Design of switching low-frequency power amplifier
Abstract
This bachelor project maps out switching technologies used in LF power electronics and gained information was consequentially used to design switching lf power amplifier as independent unit. Content of design is LF power amplified level, working on switching technology principle. Correction pre-amplifier with possibility of adjusting volume, balance h/l frequency and switching power supply is content as well too. Next part of project is familiarization s design program Eagle and optimizing program for switching power supply PXLS expert and creating constrictive basis for complete device. Last part of project is basically activation all functional part of device in one unit. Than measurement basic parameters on created functional device, graphical elaborating measurement-gained values and confrontation with catalog values. Conclusion of this project is evaluation achieved results in compare with supposed result of project- info:eu-repo/semantics/bachelorThesis
