Overview

THIS DOCUMENT IS FOR MAINTENANCE PURPOSES ONLY AND IS NOT RECOMMENDED FOR NEW DESIGNS ADVANCE INFORMATION 3797-2·2 MA818 THREE-PHASE PULSE WIDTH MODULATION WAVEFORM GENERATOR The MA818 PWM generator has been designed to provide waveforms for the control of variable speed AC machines, uninterruptible power supplies and other forms of power electronic devices which require pulse width modulation as a means of efficient power control.
The six TTL level PWM outputs (Fig.
2) control the six switches in a three-phase inverter bridge.
This is usually via an external isolation and amplification stage.
Rotational frequency is defined to 12 bits for high accuracy and a zero setting is included in or...
