主电

1）电源电压及波动。应特别注意与变频器低电压保护整定值相适应，因为在实际使用中，电网电压偏低的可能性较大。

2）主电源频率波动和谐波干扰。这方面的干扰会增加变频器系统的热损耗，导致噪声增加，输出降低。

3）变频器和电机在工作时，自身的功率消耗。在进行系统主电源供电设计时，两者的功率消耗因素都应考虑进去

体积小、容量大的驱动装置；磁铁电动机也正在开发研制之中。随着IT技术的迅速普及，变频器相关技术发展迅速，未来主要向以下几个方面发展：

网络智能化

智能化的变频器使用时不必进行很多参数设定，本身具备故障自诊断功能，具有高稳定性、高可靠性及实用性。

目前市场上新型变频器都内置了接口，同时提供多种相互兼容的通信接口，支持多种通信协议，同时可以通过连接计算机，由计算机键盘来控制和操作变频器，并且可与多种现场总线进行联网通信， 可以实现多台变频器联动，甚至是以工厂为单位的变频器综合管理控制系统。

Main power

1) Power supply voltage and fluctuation. Special attention should be paid to adapting to the low voltage protection setting value of the inverter, because in actual use, the possibility of low grid voltage is greater.

2) Main power frequency fluctuation and harmonic interference. This interference will increase the heat loss of the inverter system, resulting in increased noise and reduced output.

3) The power consumption of the inverter and the motor when it is working. When designing the main power supply of the system, the power consumption factors of both should be taken into account

Small volume, large capacity drive device; Magnet motors are also being developed. With the rapid popularization of IT technology, inverter related technologies are developing rapidly, and the future is mainly to the following aspects:

Network intelligence

The intelligent inverter does not need to set many parameters when using, and has fault self-diagnosis function, with high stability, high reliability and practicality.

At present, the new frequency converter on the market has a built-in interface, while providing a variety of compatible communication interfaces, supporting a variety of communication protocols, at the same time, you can connect the computer, by the computer keyboard to control and operate the frequency converter, and can communicate with a variety of fieldbuses, you can achieve multiple frequency converter linkage. Even inverter integrated management control system based on factory.
