碩士 === 國立中山大學 === 電機工程學系研究所 === 100 === The objective of this thesis is to design a multilevel converter circuit for driving slotless tubular linear generators (STLG) on retrieving renewable energy application. With the changing speeds and reciprocating directions of the movers, the electric energy generated from the STLG will exhibit large fluctuations and is hard to be used directly. Based on machine modeling and mover reference frame projection, a converter circuit and a data acquisition (DAQ)-based drive control scheme have been developed. From the experimental results, the control scheme implemented on the converter circuit can provide acceptable multilevel dc outputs at various operating modes.
