Figure 15-1 conceptualizes the PWM module in a
simplified block diagram. Figure 15-2 illustrates how
the module hardware is partitioned for each PWM
output pair for the Complementary PWM mode. Each
functional unit of the PWM module is discussed in
subsequent sections.
The PWM module contains four PWM generators. The
module has up to eight PWM output pins: PWM1H,
PWM1L,
PWM4H and PWM4L. For complementary outputs,
these eight I/O pins are grouped into H/L pairs.
15.2
The PWM module is designed for applications that
require:
• High-resolution at high PWM frequencies
• The ability to drive Standard, Edge-Aligned,
• The ability to create multiphase PWM outputs
For Center-Aligned mode, the duty cycle, period phase
and dead-time resolutions will be 8 ns.
Two common, medium power converter topologies are
push-pull and half-bridge. These designs require the
PWM output signal to be switched between alternate
pins, as provided by the Push-Pull PWM mode.
Phase-shifted PWM describes the situation where
each PWM generator provides outputs, but the phase
relationship
specifiable and changeable.
Multiphase PWM is often used to improve DC/DC
converter load transient response, and reduce the size
of output filter capacitors and inductors. Multiple DC/DC
converters
phase-shifted in time. A single PWM output operating at
250 kHz has a period of 4 μs, but an array of four PWM
channels, staggered by 1 μs each, yields an effective
switching frequency of 1 MHz. Multiphase PWM
applications typically use a fixed-phase relationship.
Variable phase PWM is useful in Zero Voltage
Transition (ZVT) power converters. Here, the PWM
duty cycle is always 50%, and the power flow is
controlled by varying the relative phase shift between
the two PWM generators.
