交流调速有多种方法(异步电动机的变极调速、调压调速、转子串电阻调速、电磁转差离合器调速,液力耦合器调速、机械差动调速、变频调速等),但主流是变频调速。变频调速的变频电源有旋转变频机组和静止变频装置。前者由异步或同步电动机-支流发电机和直流电动机-同步发电机两套机组组成。后者则由电力电子器件和微电子器件组成,吴可动部分。由于旋转变频机组设备庞大、有可动部分、维护量大、效率低和性能差,故已被静止变频装置代替。

静止变频装置就是现在广泛使用的变频装置,可分为交-直-交变频和交-交变频两大类,交-直-交变频又可分为电压型和电流型两大类,交-交变频多位电压型、也有少量使用电流型。变频控制方式分为电压型、电流型、脉冲宽度调制型等。其主回路的拓扑、控制策略都有多种方式可以选择,如功率器件有SCR(晶闸管,Thyristor)、GTO(门极关断晶闸管,Gate Turn-Off Thyristor)、IGBT(绝缘栅双极晶体管,Insulated-Gate Bipolar Transistor)、IGCT(集成门极换流晶闸管,Integrated Gate Commutated Thyristor,是一种新型半导体功率器件,在GTO的基础发展起来的)等;主回路的拓扑结构可选择两电平、三电平、负载换相式SCR电流型变频器等,控制策略可选择V/f控制、矢量控制、直接转矩控制、脉冲宽度控制(PWM)或脉冲幅度调制(PAM)等,电压也有高压(3~6kV,主要是大容量的同步或异步电动机)、中压或低压(如一般的小功率380V和轧钢辅传动的电动机)等,一般地说,1000kW以下的电动机较适合采用IGBT的通用变频器。国外电气公司,如德国西门子、法国阿尔斯通、瑞典ABB、美国GE、意大利ANSOLDO、日本日立、日本三菱、日本安川等公司都生产各种容量、不同电压的通用变频器可供选用,选择时可适当参照其业绩及在类似或同样机组使用情况和经验与效果。
变频所用电动机也需注意,一般1000kW以下的电动机,采用异步电动机性能价格比较好,对于容量较大的可采用同步电动机或异步电动机。异步电动机一般采用线绕电机,而容量较小的电动机一般采用鼠笼电机。由于传动控制系统一般采用PWM变频器,故电机也须特殊设计,以满足PWM变频调速的要求(按不同机组情况,包括允许过载%、过载时间、工作制、绝缘等级、保护等级、额定电压等)。
