| Summary: | 碩士 === 國立雲林科技大學 === 電機工程系碩士班 === 95 === This thesis presents the analysis, design and implementation of an active-clamp
Zeta converter and Zeta-Flyback converter. Adding RCD snubber circuit in the
conventional Zeta converter can restrain spike voltage and spike current. In the
conuention hard switching conuerters, the main drawbacks are large switching and
conduction losses. Theactive clamp technique applied ti Zeta converters is discussed in
this thesis. The active-clamp technique is advanced by the thesis. Using active-clamp
technique can absorb the energy stored in the leakage inductance of transformer. So it
reduces the voltage and stress of power switchies. In addition, the proposed circuit can
achieve zero voltage switching(ZVS) turn on.
Finally experimental results are presented to verify the circuit performance of the
Zeta-Flyback converter.
