船舶起货机用节能型变频器研制

The Research of Energy-Saving Type Frequency Converter-Using in Ship's Cargo Winch

介绍船舶起货机用节能型变频器。该变频器采用变频调速、能量回馈与控制三部分，实现正常起货的变频调速系统，当货物下降时，采用逆变使能量回馈到电网，达到2次节能目的。

This paper introduces the energy-saving type frequency converter using in ship's cargo winch. This kind of frequency converter contains varying frequency for speed regulation,energy feedback and control system. When lowing theloads,it can invert and feed the energy back to the electric powec network so that energy is saved again.
