Small-signal analysis of boost converter, including parasitics, operating in CCM

This paper presents the various principles of statespace averaged modeling of DC-DC Boost converters operating in the continuous conduction mode (CCM). The average model technique, the time average algorithm, and the energy conservation laws are used. Also, the output transfer function of a Boost converter is derived which can be used for designing a robust controller. Furthermore, the effects of parasitic elements and losses are included based on the state-space averaging technique. The open loop transfer functions of the proposed models are derived and the behavior of the converter is verified by the transient step responses.
