碩士 === 國立中央大學 === 電機工程學系 === 104 === The thesis presents an improved non-isolated boost DC-DC converter. The boost DC-DC converter has been widely applied on renewable generation and energy storage. Improved circuit proposed in this thesis is divided into two stages through three IGBT switches to perform the control. The first stage is a modified circuit architecture of the input current ripple complementary boost converter. The current ripple through two switches can be effectively reduced by inversely operating. This approach not only enables a more stable input source but also reduces the high current carrying stress of single inductor. Through the proposed single-sided multiple pulse width modulation control the input current ripple can be maintained in a minimum range at any duty ratio. The second stage apply switched-inductors replaced for a single inductor to increase the voltage gain ratio. Finally, a boost converter with an input voltage of 40~60 V, an output voltage of 150~400 V, and output power of 300 W is implemented. The experimental results are verified with theoretical analysis of the proposed structure.
