MOTOR CONTROL PWM

MODULE

This module simplifies the task of generating multiple,

synchronized Pulse-Width Modulated (PWM) outputs.

In particular, the following power and motion control

applications are supported by the PWM module:

• Three-Phase AC Induction Motor

• Switched Reluctance (SR) Motor

• Brushless DC (BLDC) Motor

• Uninterruptible Power Supply (UPS)

The PWM module has the following features:

• 6 PWM I/O pins with 3 duty cycle generators

• Up to 16-bit resolution

• ‘On-the-Fly’ PWM frequency changes

• Edge and Center-Aligned Output modes

• Single Pulse Generation mode

• Interrupt support for asymmetrical updates in

Center-Aligned mode

• Output override control for Electrically

Commutative Motor (ECM) operation

• ‘Special Event’ comparator for scheduling other

peripheral events

• Fault pins to optionally drive each of the PWM

output pins to a defined state

This module contains 3 duty cycle generators,

numbered 1 through 3. The module has 6 PWM output

pins, numbered PWM1H/PWM1L through PWM3H/

PWM3L. The six I/O pins are grouped into high/low

numbered pairs, denoted by the suffix H or L,

respectively. For complementary loads, the low PWM

pins are always the complement of the corresponding

high I/O pins.

The PWM module allows several modes of operation

which

are

beneficial

for

specific

power

control

applications.
