| This thesis begins with an investigation into the application of optimization techniques to the design of switch-mode power supply. Based on the findings, a fuzzy nonlinear optimization approach to power electronic circuit and system design is proposed. A software tool MATSPICE that implements the proposed design approach is developed for power electronics applications. The software integrates the simulation function of PSpice and the optimization of MATLAB.; With the aid of MATSPICE, various novel switch-mode power supply designs with power-factor-correction, battery back-up, soft-switching, fast output regulation are developed. Such designs are optimized using MATSPICE to achieve best performance. Detailed analyses are performed to identify the operation and performance of the novel switch-mode power supply designs. Hardware are also constructed to confirm the theoretical predictions.; This thesis concludes with a summary of the work has been done and suggestions for further enhancement of MATSPICE. |
