| Summary: | This project describes the developement of a simple and low cost computer controlled pulse width modulation (PWM) inverter for AC variable speed drives. A fully digital EPROM-pased pulse width modulation contains a different frequency of PWM waveform capable driving of the trassitorised inverter to generate variable frequency output. This modulator is simple and dynamically better in comparation with one built using a microcomputer. A high-1 resolution (one in 256 ) is obtained, and up to eight different PWM switching strategies can be easily implemented. The computer is linked to the various sub-system through a serial interfacing unit via R232 output port The software developed is flexible and can be furthure modified to accommodate any variation in operating procedures. |
