Nonlinear control and operation of DC to DC switching power converters
Conventional control of switching power conversion is based on a linear model of the system, which limits its scope and performance. This thesis addresses a family of control and operation issues that arise from the nonlinear nature of the switching power conversion. The focus is on dc to dc power …

Small signal analysis of nonlinear systems with periodic operating trajectories
A new method for small-signal analysis of switching power converters is developed and implemented in a computer program. The method is derived for systems where the nonlinearities can be described by elements that can take on one of two values, based upon a controlling variable. Another requirement …

Self-Oscillating Unified Linearizing Modulator
… buck-boost derived pulse-width modulation dc-dc converters suffer from the large-signal control-to-output nonlinearity. Without feedback control, the large-signal control-to-output nonlinearity would lead to output overregulation and even damage the components. The control gain is defined as the …
