Different circuit connections are explored here. For instance, an inversion of source and load converts the buck converter into a boost converter, the cascade connection of the converters leads to the formation of the buck-boost, and the Cuk converter from the basic buck and boost converters.

An analysis of the concepts and variables associated with state-space, canonical and system transfer function representations of the common converters. In direct circuit linearization averaging technique, dynamic behavior of the circuit cannot be studied at the resonant frequency as the switching frequency component of the output for the resonant converter is different from the local average value frequency. Thus, the integral expression of the average value needs to be extended using the Fourier series; and the derivative expression with respect to a particular frequency is required for the dynamic analysis.

The basic converters complete equivalent circuits can be studied here which include the basic AC modeling approach and the results for several converters. A simple circuit diagram is used for high-frequency converters. We will construct the non-linear model and convert it into a linear circuit that describes the small-signal performance of a circuit.
