Abstract
The invention discloses a large-current high-frequency reactor. The large-current high-frequency reactor comprises a magnetic core which is installed through an upper clamping piece, a lower clamping piece and a fastening piece, wherein the magnetic core is of a hollow square structure, coils are wound on two core columns of the magnetic core, each coil is divided into an upper section and a lower section, and the upper section and the lower section are electrically connected through a busbar. The large-current high-frequency reactor is characterized in that the magnetic core is made of an iron silicon aluminum magnetic powder core and the coils are aluminum wires and are vertically wound in an 8-shape. The large-current high-frequency reactor has the advantages that the efficiency of a photovoltaic inverter is improved; on the premise that the original product performance and technical parameters are improved, the current production cost is greatly reduced and the environmental protection and energy saving concepts are realized at the same time.
