Zusammenfassung:The utility model discloses a current sharing measuring apparatus of a large-power rectification apparatus. The current sharing measuring apparatus comprises a sampling circuit, a front amplification circuit, a signal isolation circuit, an amplification output circuit and a comparison circuit which are successively connected. The current sharing measuring apparatus of the large-power rectification apparatus has the advantage of solving the problem that the performance of a conventional rectification apparatus is reduced because large-power controlled silicon is not conducted due to incapability of predicting damage of a fuse in real time in the prior art.
