Abstract

A fully digital erasable programmable ROM (EPROM)-based pulse width modulator (PWM) that 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 than 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 presented
