Design and Models Validation of the Multiphase Interleaved Boost Converter for Special Applications

The interleaved parallel technique has been widely investigated for its flexibility in extending the output power of DC-DC converters while effectively reducing the input and output ripple. This paper focuses on the research of high-power interleaved three-level boost converter topology with low ripple and high efficiency. Firstly, the application of the overall system, control strategy, modulation method are introduced, and its effect on output voltage ripple is verified and compared by simulation. It is planned to build a 20kW prototype platform for subsequent experiments. The results will build a technical foundation and provide a reference for the application of the interleaved parallel three-level boost converter topology to subsequent research in related fields.
