Abstract: The investigation in this thesis begins with modeling and control of high-order DC-DC converters. Generalized state-space modeling, especially reduced-order state-space modeling method, is used to design suitable controllers for advanced DC-DC converters. An improved Sliding Mode (SM) controller is proposed for advanced DC-DC converters. The theoretical analysis and experimental results show the proposed SM controller can make smaller surges in the currents and voltages and largely suppress the output voltage error. For topology development, a set of Voltage-Lift Split-Inductor-type boost converters is introduced, which can get much higher step-up voltage transfer gain. Secondly, a set of Voltage-Lift-type Switched-Inductor cells are proposed to get higher voltage transfer gain, which can be applied to all the basic DC-DC converters. At last, N-Switched-Capacitor buck converters are proposed to get even higher step-down voltage transfer gain. Compared to the traditional methods, these newly proposed converters can be applied to some extreme applications where steep voltage transfer gain is required with simple structures and good performances.
