| Abstract: | 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. |
