ABSTRACT: The South American rice water weevil Oryzophagus oryzae (Costa Lima) (Coleoptera: Curculionidae) is a key pest of irrigated rice in Brazil. Light traps could be used as an integrated pest management (IPM) strategy since these weevils have s

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 circ

The leakage currents caused by high-frequency common-mode (CM) voltage have become a major concern in transformerless photovoltaic (PV) inverters. This paper addresses to a review on dc-ac converters applied to PV systems that can avoid the circulati
