Application Note

From an inspection of
Figure 3
, it may be difficult to see why one PWM
waveform is preferred over another in a motor control application. If
you're looking for the best resolution possible at a given PWM frequency,
consider using edge-aligned mode.
Figure 3
shows that for the same
PWM waveform period, edge-aligned operation allows the counter
modulus to be twice as high as that of center-aligned mode, thereby
doubling the PWM resolution. However, for most motor control power
stages that use multiple half bridge transistor arrangements, the benefits
resulting from the interaction between center-aligned PWMs justify their
selection. More on this later.
Together, or not Together . . . That is the Option
The 'MP16 PWM module can generate up to six independent PWM
signals, all synchronized to the same counter/timer. If that isn't enough,
three additional PWM signals can be obtained from the timer modules,
two of which are synchronized to a separate time base, and the third
synchronized to still another time base. In other words, a total of nine
independent PWM signals are possible from the 'MP16, running at up to
three different PWM frequencies.
Figure 4
shows the familiar IGBT half bridge used with many motor
drives. In some instances, it is desirable to control these devices in a
complementary fashion such that when one device is on, the other is off,
and vice versa. However, if power is applied across the half bridge, you
never want to have both transistors on at the same time, since fire,
smoke, and other unpleasantries may result.
To drive the transistors in a complementary fashion, the 'MP16 provides
a separate operating mode specifically for this purpose. By setting the
INDEP bit in the CONFIG register to 0, the six PWM signals are
configured as three pairs of complementary PWMs. This is extremely
useful when controlling a 3-phase power module, such as the
VersaPower module available from Motorola and shown in
Figure 5
.
