| Abstract: | Making use of the special LSIC SA4828 to design an inverter for AC motor driver can greatly simplify both the hardware and software.The SA4828 used as SPWM signal generator controls the IPM via driver circuits to produce variable frequency power supply.The speed adjusting system consisting of SCC,KB,LED display and speed coder is tested and excellent performance is achieved.The tested data shows that the motor can run smoothly from 1 to 50 Hz and the speed adjustment accuracy is up to 0.1%.It can be concluded that designing inverter by means of SA4828 is a convenient and practical method. |
