Analysis of a Non-Isolated Interleaved DC-DC Boost Converter with a Voltage Doubler Cell in Discontinuous Conduction Mode

This paper presents an investigation of discontinuous conduction mode (DCM) of a two-phase interleaved dc-dc boost converter with a voltage doubler cell. Comparing to the conventional boost converters, the proposed converter in DCM can easily achieve a high voltage gain with continuous input current and with lower voltage stress on components. These features give the proposed converter the advantage to be used in many applications, especially renewable energy applications. The topology is simulated to verify the steady-state analysis. Moreover, experimental validation is presented to verify the mathematical analysis and simulation results. The overall results of the calculations, simulations, and experiments prove the validity of the proposed analysis of the topology in DCM.
