| Abstract: | A three-phase SPWM variable frequency power supply was designed by using the microcomputer as controller and Combining special-purposed SPWM integrated circuit.The main circuit adopted AC-DC-AC structure. The control circuit of the system was formed by the 8051 microcontroller , three-phase SPWM generate integrated circuit SA4828 and a few peripheral chip of expansions.The system has realized total digitization controls on variable frequency power supply. |
