摘要
研制了一种由８０９８单片机和新型专用脉宽调制集成电路ＭＡ８１８组成的变频调速系统．该系统最大输出频率为２ｋＨｚ，载波频率固定为１５．６ｋＨｚ，输出频率分辨率为１２位．论述了系统的工作原理、控制方法及调试经验，给出了带载实验波形．
A VVVF system accomplished by using a single-chip micro-controller 8098 and new special purpose PWM IC MA818 is proposed. The highest output frequency is 2kHz and the carrier frequency is 15.6kHz. The resolution of frequency is 12 bits in whole scale. The operating principle and control method are introduced. The voltage and current waveforms on driving a highspeed motor are given lastly.
