摘要
介绍了交流调速的控制原理、交流变频调速的U/F协调控制、矢量控制、直接转矩控制方式，变频器的性能及应用。通过对用于水泵、通风等场合的变频器的节电分析、计算，节能效果明显。指出了变频器的全数字控制、PWM控制等发展趋势，以及如何消除使用变频器造成的谐波干扰。
The article introduces the ways of U/F coordinate control, vector control and direct -torque control on inverter. It analyses and calculates the energy - saving efficiency applications of inverter for pumps and fans. And it explains the integrative pump controlled（IPC） system and energy -saving efficiency of inverter used in all trads. Also it describes the control - technology development trend of inverter with DSP chips and PWM etc. , and the harmonic of inverter produced is suppressed.
