SA828 Family Three-Phase PWM Waveform Generator DS4226 - 2.0 November 1996 The SA828 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
