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:

• 8 PWM I/O pins with 4 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

• Duty cycle updates are configurable to be

immediate or synchronized to the PWM time base

This module contains 4 duty cycle generators, num-

bered 1 through 4. The module has 8 PWM output pins,

numbered PWM1H/PWM1L through PWM4H/PWM4L.

The eight 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 pin.

The PWM module allows several modes of operation

which are beneficial for

specific

power control

applications.
