摘要：通过从如何减小逆变器的装置容量入手，根据矿井提升机的工艺特点,给出了斩波串级调速系统逆变变压器容量的设计方法。分析了斩波串级调速系统的主电路，研究了基于斩波串级调速系统的逆变器容量。与普通串级调速系统相比，斩波串级调速系统逆变器的容量大为减小；大大改善了电机拖动系统的功率因数。

Abstract: From the angel of minimizing the inverse transformer capacity, a method to design inverse transformer capacity based on the technical features of minewell hoist was given. Main circuit in chopwave cascade speedregulation system was analyzed. Inverter capacity based on chopwave cascade speedregulation system was studied. Compared with cascade speedregulation system, inverter capacity of chopwave cascade speedregulation system was decreased, and power factor was increased greatly.
Key words: inverse transformer; chopwave cascade; minewell hoist
