Steady state analysis of Quasi Switched Boost DC-DC converter in CCM

Abstract

This paper presents the steady state analysis Quasi Switched Boost (QSB) DC-DC converter. QSB impedance network has only one inductor and one capacitor unlike Z-Source/Quasi-Z-Source which have two inductors and two capacitances in their impedance network but QSB impedance network has one more active switch, one more diode than Z-Source/Quasi-Z-Source impedance network. The DC voltage gain for ideal and non-ideal QSB DC-DC converter has been derived. Further the minimum inductance has been design to mark the boundary between (CCM) and Discontinuous Conduction Mode (DCM). The overall power loss has been calculated by considering the all parasitic of non-ideal Quasi-Switched Boost Dc-Dc converter. Further the efficiency analysis has been done by considering its overall power losses.
