Abstract

This bachelor's thesis deals with the design of a three-phase thyristor AC-AC voltage converter. The aim is to explain the operating principle of the mentioned converter, including the requirements for switching sequences for control of its power part. The design of the power structure, control pulses, circuits for synchronization with the power grid, and thyristor triggering was the next step of the work. The realization of the project required the use of engineering software Eagle PCB, which is used for the design of electronic circuits and printed circuit boards. The next step was the practical implementation of all proposed designs – assembly of components on the printed circuit board and subsequent testing of individual blocks of the device. The results of the measurements confirmed the correctness of the individually tested parts of the converter. The device is ready for the complex power up and future implementation of the control algorithms now.
