9Dynamic Modeling of PCM/PVM-Controlled CF Converters
9.1 Introduction
As discussed in Chapter 4, the peak current-mode (PCM) control would provide highly desirable features, especially in the voltage-fed buck-type converters [1,2]. The PCM-controlled converters have also been applied in interfacing the photovoltaic (PV) generators into the rest of the system [3,4]. It was noticed earlier that the application of PCM-controlled buck converter in PV applications could lead to system instability. The origin of the instability was later addressed to the cascaded nature of the control under PCM control in Ref. [5]. The dynamic modeling of the converter under PCM control can be performed by applying exactly the same methods as have been introduced ...
