Abstract
This article proposes a double-line-frequency current ripple (DLFCR) reduction strategy for the photovoltaic microinverter. A power predictive scheme is established according to the output power mathematical model of the prestage full-bridge dc-dc converter (PFDDC), which is the basis of the proposed DLFCR reduction strategy. The control effect is analyzed with considering parameter estimation error, and the analysis results show that the proposed strategy has good dynamic performance and robust performance. The small-signal model of the PFDDC has been established to design the voltage-loop parameters. The bandwidth of the system controlled by the power predictive scheme is large, which can effectively reduce the design complexity because no parameter is needed to design for power prediction. Experimental verifications are presented to verify the analysis.
