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.

Discussed here are the discontinuous conduction mode, mode boundary, and conversion ratio of simple 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.

When an AC current flows through a conductor, outer filament of that conductor carries more current as compared to the filament closer to its center. This results in higher resistance to AC than to DC and is know as skin effect. Proximity effect, the alternating flux in a conductor is caused by the current of the other nearby conductor.
