变频器的制造专门化，可以使变频器在某一领域的性能更强，如风机、水泵用变频器、电梯变频器、起重机械变频器、张力控制变频器等。除此以外，变频器有与电动机一体化的趋势，使变频器成为电动机的一部分，可以使体积更小，控制更方便。 

化

随着矢量控制、转矩控制等控制理论的发展和高速数字信号处理器的应用，变频器的性能将越来越高。无速度传感器矢量控制技术的发展成熟，使变频系统摆脱了硬件检测电机转速的束缚，系统体积更小。 

数字化程度

受益计算机技术的进步，变频控制系统将实现交流调速系统和信息系统的紧密结合，同时还可以系统的整体性能。另外，随着交流电机控制理论的日益丰富，相关的控制策略和控制算法也越来越复杂，需要更多的计算和存储空间，目前全数字化的交流调速系统中都广泛的应用DSP芯片。 

节能环保无公害

变频器的电磁兼容、谐波抑制、电机噪声抑制等技术都是目前人们关注的重点，变频器的环保问题显得越来越重要。很多国家都已经制定了限制谐波的有关规定和标准。寻找解决好变频器的噪声和电磁污染的方法，也成为了很多研宄人员工作的重心。 

适应新能源

现在以太阳能和风力为能源的燃料电池以其低廉的价格崭露头角，有后来居上之势。这些发电设备的大特点是容量小而分散，将来的变频器就要适应这样的新能源，既要高效，又要低耗。现在电力电子技术、微电子技术和现代控制技术以惊人的速度向前发展，变频调速传动技术也随之取得了日新月异的进步，这种进步集中体现在交流调速装置的大容量化、变频器的化和多功能化、结构的小型化等方面。
