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.
