摘要：

In response to the problem of unstable interaction in two-stage photovoltaic power generation systems, a mathematical model of the two-stage photovoltaic system was first established, and then a mathematical model of a capacitor converter based on Buck/Boost converter was established to simulate the capacitor. Subsequently, from the perspective of harmonic suppression, the working principles of suppressing oscillations of capacitor converters under parallel adaptation were analyzed, and the effectiveness of capacitor converters was verified through simulation.
