Nonlinear Large-Signal Modeling of PWM DC-DC Switching Power Converters

摘要

Based on switching function, this paper presents a general unified nonlinear large-signal equivalent circuit model and its mathematics description, which can be used to describe PWM switching converters operating in all the possible modes, such as continuous conduction mode (CCM), discontinuous inductor current mode (DICM), discontinuous capacitor voltage mode (DCVM) and discontinuous quasi-resonant mode (DQRM), etc.
