Abstract

In this brief, extension of known rules for designing optimized single-resonant ac current regulators to multiresonant current regulators parameter selection for single-phase grid-connected photovoltaic inverters is proposed. The proposed generalization is made possible by utilizing multiplied rather than summed resonant terms within the controller. A set of phase-margin oriented design guidelines is established, explicitly defining each controller parameter to corresponding figure of merit. Simulations and matching experimental results are shown to verify the proposed approach.
