摘要：
A fully digital EPROM-based pulse width modulator (PWM), which receives voltage and frequency control commands independently at the input and could be used in ac variable-speed drives, is described. This modulator is simpler and dynamically better in comparison 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. Changes in the voltage or frequency commands are transient free. Some experimental results are included.
