| Summary: | Photovoltaic generators constantly change their maximum power point (MPP) because solar radiation and temperature at different times of the day are always different. The boost DC-DC converter used in energy conversion is controlled when solar radiation and environmental temperature changes are complex. These difficulties make it challenging to design control laws. Fast and reliable step-up DC-DC converters face many obstacles when applied in the field of high-capacity urban trains, causing the current quality of the conversion
process to be limited. This paper proposes a multilevel boost DC-DC converter based on MMC configuration, applying the PWM modulation method and INC maximum power point tracking (MPPT) algorithm. MMC boost DC-DC converter can provide an N times conversion ratio and has a much lower operating frequency than conventional Boost Converter. The process of evaluating the effectiveness of the proposed converter configuration and the algorithm is performed on Matlab/Simulink software, and the output parameters of the
conversion process are compared with a conventional Boost DC-DC converter based on published analyses. |
