摘要：
The photovoltaic maximum power point tracking (MPPT) strategy for the system, which is configured with boost full-bridge isolated DC-DC converters (BFBIC) in input-parallel output-series (IPOS) structure, is studied via analyzing the converter operating characteristics with small signal analysis method. In order to meet the practicality in engineering, a new MPPT algorithm which can be coupled with DC-DC converter dual-loop control and based on the constant voltage method and the perturbation observation method is proposed. It accurately approximates the maximum power point by sampling three points with variable step size for comparison. By building a model in PSIM for simulation, the results show that the effectiveness and better tracking effect of the new MPPT strategy are verified. © 2022, Solar Energy Periodical Office Co., Ltd.
