14.0
The dsPIC33FJ12MC201/202 device supports up to
two dedicated Pulse Width Modulation (PWM)
modules. The PWM1 module is a 6-channel PWM
generator, and the PWM2 module is a 2-channel PWM
generator.
The PWM module has the following features:
• Up to 16-bit resolution
• On-the-fly PWM frequency changes
• Edge-Aligned and Center-Aligned Output modes
• Single Pulse Generation mode
• Interrupt support for asymmetrical updates in
• Output override control for Electrically
• Special Event comparator for scheduling other
• Fault pins to optionally drive each of the PWM
• Duty cycle updates configurable to be immediate

14.1
This module simplifies the task of generating multiple
synchronized PWM outputs. The following power and
motion control applications are supported by the PWM
module:
• 3-Phase AC Induction Motor
• Switched Reluctance (SR) Motor
• Brushless DC (BLDC) Motor
• Uninterruptible Power Supply (UPS)
This module contains three duty cycle generators,
numbered 1 through 3. The module has six PWM
output pins, numbered PWM1H1/PWM1L1 through
PWM1H3/PWM1L3. 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 pin.
14.2
This
complimentary PWM outputs that can be used for:
• Independent PFC correction in a motor system
• Induction cooking
This module contains a duty cycle generator that
provides two PWM outputs, numbered PWM2H1/
PWM2L1.
