An Interleaved Non-Isolated DC-DC Boost Converter with Voltage Doubler Cell in CCM

This paper introduces an interleaved non-isolated of a boost converter with voltage doubler cell in continuous conduction mode (CCM), which can be used in many renewable energy applications, such as photovoltaic (PV) and fuel cells. The proposed converter consists of two stages. The first stage is a two-phase interleaved boost stage, and the second stage is voltage doubler voltage multiplier. Due to these two stages, the proposed converter produces twice the voltage gain of the conventional boost converter while maintaining the continuity of the input current and with lower stresses on components. The analysis and design procedure of the proposed converter is discussed in this paper. Also, a simulation tool is used to verify the steady-state analysis of the converter. Finally, a hardware prototype was executed in the laboratory to convert 15 to 200 Vdc to confirm the theoretical analysis and simulation results.
