The paper does not explicitly mention the limitations of the research.
1：Experimental Design and Method Selection:
The paper proposes a new MPPT control method based on multi-phase multi-stage IBCs for high voltage gain from PV panel. The system is modeled and simulated in Matlab/Simulink.
2：Sample Selection and Data Sources:
PV panel specifications are provided, including maximum power, open circuit voltage, voltage at Pm, short circuit current, current at Pm, irradiance, and temperature.
3：List of Experimental Equipment and Materials:
IGBTs are selected as power switches due to high performance at high voltage level and low switching frequency.
4：Experimental Procedures and Operational Workflow:
The system is designed with four-phase IBC for the first stage, three-phase IBC for the second stage, and two-phase IBC for the last stage. PWM pulse generator is used to generate pulses for each switch based on the reference signal produced by the InC MPPT controller.
5：Data Analysis Methods:
The output voltage and current of each stage are analyzed, along with inductor current on CCM for each stage and the comparison of output power with input power.
