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.

SA828  
Information contained within the pulse width modulated  
sequences controls the shape, power frequency, amplitude,  
and rotational direction (as defined by the red-yellow-blue  
phase sequence) of the output waveform. Parameters such as  
the carrier frequency, minimum pulse width, and pulse delay  
time may be defined during the initialisation of the device. The  
pulse delay time (underlap) controls the delay between turning  
on and off the two power switches in each output phase of the  
inverter bridge, in order to accommodate variations in the turn-  
on and turn-off times of families of power devices.  
The SA828 is easily controlled by a microprocessor and its  
fully-digitalgenerationofPWMwaveformsgivesunprecedented  
accuracy and temperature stability. Precision pulse shaping  
capability allows optimum efficiency with any power circuitry.  
The device operates as a stand-alone microprocessor  
peripheral, reading the power waveform directly from an  
internal ROM and requiring microprocessor intervention only  
when operating parameters need to be changed.  
An8-bitmultiplexeddatabusisusedtoreceiveaddressesand  
data from the microprocessor/controller. This is a standard  
MOTELTMbus,compatiblewithmostmicroprocessors/controllers.  
Rotational frequency is defined to 12 bits for high accuracy  
and a zero setting is included in order to implement DC  
injection braking with no software overhead.  
This family is pin and functionally compatible with the  
MA828 PWM generator . Two standard wave shapes are  
available to cover most applications. In addition, any  
symmetrical wave shape can be integrated on-chip to order.
