摘要：

This work proposes the application of an active filtering method to compensate the dc-link low frequency voltage ripple of a 250 W two-stage PV micro-inverter. A bidirectional buck-boost converter was chosen as an auxiliary ripple energy storage circuit connected to the dc-bus of a full-bridge grid-tied inverter. Only thin-film capacitors were used in the prototype seeking to increase lifetime. The paper introduces the inverter circuit, the origin of low-frequency ripple in single-phase applications and presents full theoretical analysis of the buck-boost operating as active filter. Experimental results reveal satisfactory and expected circuit behavior and the dc-link voltage ripple has its amplitude reduced almost four times using the method.
