The frequency response problem of a switching dc-to-dc converter system is the problem of computing the small-signal frequency response of the system with respect to its inputs. It arises in the study of the small-signal behavior and in the design of a feedback controller for the dc-to-dc converter system. The analytical solution of the problem is discussed in this thesis. There are previous efforts in developing approximate analytical methods for solving the problem; however, these methods are unsatisfactory. The Small-Signal Frequency Response Theory presented in this thesis is a mathematical theory for the linearization of an ideal dc-to-dc converter system in the vicinity of its steady-state solution. It is developed to overcome the problems encountered in the application of the approximate analytical methods. The theory is exact in the small-signal limit, and the results given by the theory is valid at all frequencies provided that the system model used in the calculation of frequency response is valid at all frequencies. The theory has the best of both the time-domain approach and the frequency domain approach for the analysis of switching dc-to-dc converter systems. The theory results in significant impact in the fields of computer-aided design and modeling and analysis in power electronics.
