Abstract
Aiming at the mixed AC load composed of various nonlinear loads and asymmetric loads encountered in photovoltaic inverter application scenarios, this paper takes three-phase four-leg inverter as the research object. After analyzing common PR control and repetitive control, a composite control strategy based on multiple PR control and repetitive control is proposed. Through low-power experiments, the advantages of compound control in steady-state performance and dynamic performance are verified.
