恒压供水变频调速装置的研究

Research of Common Pressure Regulation Water Supply System with Frequency Conversion Timing Technique

本文阐述恒压供水变频调速装置采用SAMOC-Vm05变频器,该变频器由IGBT构成,并采用三相正弦脉宽调制方式控制。文中介绍了三相正弦脉宽调制式变频器的控制算法实现原理,变频器控制系统电路的设计特点、抗干扰及治理高次谐波的措施。

This common pressure regulation water supply system consists of SAMCO-Vm05 inverter. The inverter in this system consists of IGBT. SPWM is adopted. This paper introduces the basical control algorithms and realizes the principle of three phase SPWM inverter and design characteristic of the control system circuits,anti-interference and disposes the low order harmonics.
