Presents an analysis, development of a model, and design of an experimental power supply typically used to drive high voltage and high frequency equipment. This power supply differs from conventional ones in that it used two series loaded resonant converters placed in parallel where the output voltage, the sum of both converters, is regulated shifting the voltage phase on one of the converters.

High performance ac-to-dc converters are required to meet the regulation standards to suit wide variety of applications. This thesis presents the steady state analysis, design and operation of high frequency (HF) transformer isolated resonant converters on the single phase utility line as a low harmonic controlled rectifier. Two resonant converter configurations of third order have been studied namely the LCC-type parallel resonant converter also popularly known as series-parallel resonant converter (SPRC) and the hybrid parallel-series resonant converter bridge (HPSRCB). These converters are operated at HF using variable frequency as well as fixed frequency control and they operate in different modes depending on the choice of switching frequency and load. The variable frequency SPRC is operated in discontinuous current mode (DCM), to obtain low line current total harmonic distortion (T.H.D.) and high power factor (pf), without using active control. State space analysis has been presented for one of the predominant circuit modes encountered during its operation in DCM. The various design constraints for operating the resonant converter on the utility line for high pf operation have been stated for different control schemes. In addition, steady state analysis, design optimization carried out for dc-dc converter have been presented. The effect of resonant capacitor ratio on the converter performance characteristics have been studied. SPICE3 simulations and experimental results obtained from a 150 W converter are presented to verify the theory. Continuous current mode (CCM) operation of the SPRC, and its effect on the line current T.H.D. and pf are studied. Both fixed and variable frequency control schemes have been used to control the SPRC. Complex ac circuit analysis method has been considered as the design tool to get the design curves and design of the SPRC operating on the utility line. SPICE3 simulation results for open loop operation and experimental results for both open as well as closed loop operations (active control), for two capacitance ratio's have been presented to verify the converter performance. It is shown that nearly sinusoidal line current operation at unity pf can be obtained with closed loop operation. A HPSRCB has been proposed and operated at very high pf on the utility line as a controlled rectifier. Some of the predominant operating modes of the fixed and variable frequency HPSRCB have been identified. The steady state analysis using state space modeling presented for a dc-to-dc converter has been extended to analyze the ac-to-dc converter. Using the large signal discrete time domain model, the time variation of line current and line pf have been predicted using PROMATLAB for both fixed and variable frequency operations of HPSRCB on the utility line. SPICE3 simulation results without active control and experimental results obtained from the bread board model for both open as well as closed loop fixed and variable frequency operations have been presented to verify the theory and design performance.

Future Naval systems and ships are being designed with pulse-power loads and hybrid electrical systems. There is a demand for efficient, reliable, and durable compact power converters to bridge pulse-power systems with the electrical plants of the future. This thesis presents modeling and analysis of a constant power Series Loaded Resonant (SLR) converter. The modeling work presented was successfully implemented in Simulink and then prototyped in a small-scale application in the laboratory. The Simulink model and prototype were tested under various conditions and may be used to reduce the risk in the design of future large-scale applications.
