PWM inverter controller with wave form memory |
摘要 |
A programmed PWM controller for controlling an inverter is provided which includes memory means for storing a plurality of drive data words representing a pulsewidth modulation sequence, each drive data word including a driveword and a drivetime word, the drivewords being used to operate the inverter; first digital means for selectively retrieving each of the plurality of drive data words from the memory means according to the pulsewidth modulation sequence in response to a next drive data word request signal; and second digital means governed by the drivetime word for generating the next drive data word request signal.
