Design of rotating rectifier for synchronous generator
Skurka, Tomáš ; Cibulka,, Tomáš (referee) ; Ondrůšek, Čestmír (advisor)
This diploma thesis is focused on the design of a rotating rectifier for a synchronous generator. Based on defined requirements, the new rotating rectifier concept has been created that allows a greater current range than existing rectifier used by Siemens Electric Machines s.r.o. The thesis is divided into five parts. The first part deals with the search of existing rotating rectifiers and other design possibilities. The requirements for the rotating rectifier were defined in the second part of the thesis. The following section deals with both electrical design of rectifier elements and varistors. The fourth part of the diploma thesis describes the thermal analysis. On the basis of thermal analysis the operating conditions of the rotating rectifier were determined. The last part of the thesis is devoted to mechanical and modal analysis. Based on these analyses, the strength and operability of the new rotating rectifier concept were verified.

Design of PMSG for micro hydro power plant
Skurka, Tomáš ; Ondrůšek, Čestmír (referee) ; Huzlík, Rostislav (advisor)
This bachelor’s thesis deals with a design and simulation of various implementation of the synchronous generator for a low-speed waterwheel. The construction of the generator was implemented as the radial synchronous generator with the permanent magnets on the rotor’s surface. In the introduction the reader gets familiar with the theory describing the construction of the synchronous generator with the permanent magnets intended for the small hydroelectric power plants. Within the thesis the author shows his own design of the generator and the optimization using the genetic algorithm. Next, three proposals with the predefined sheets are presented. Every single proposition of the generator was simulated in the software ANSYS Maxwell. Finally, the heat calculation was made for the certain designed variations of the generator.
