Analysis and Modeling of a Non-Isolated Two-Phase Interleaved Boost Converter with Diode-Capacitor Cells in the DCM

Abstract

In this paper, a two-phase interleaved dc-dc boost converter with two cells of diode-capacitor is analyzed and investigated in discontinuous conduction mode (DCM). Furthermore, mathematical modeling with a component selection procedure is discussed in this study. The mentioned converter is used to convert 10 V to 202.08 Vdc, which can be used in many renewable energy applications, such as photovoltaic (PV) and fuel cells. To verify the mathematical analysis and the simulation, a hardware prototype was built and implemented in a laboratory. Also, the experimental results have been compared with the proposed simulated model. The final results show consensus between mathematical expressions, simulated results, and measured results, which verifies the effectiveness of this proposed converter in the DCM.
