dsPIC33E/PIC24E Family Reference Manual

14.1 INTRODUCTION

This section describes the High-Speed Pulse-Width Modulator (PWM) module and its

associated operational modes. The High-Speed PWM module in the dsPIC33E/PIC24E

device family supports a wide variety of PWM modes and is ideal for power

conversion/motor control applications. Some of the common applications include:

• AC-to-DC converters

• DC-to-DC converters

• AC and DC motors: BLDC, PMSM, ACIM, SRM, etc.

• Inverters

• Battery chargers

• Digital lighting

• Uninterrupted Power Supply (UPS)

• Power Factor Correction (PFC) (e.g., Interleaved PFC and Bridgeless PFC)

14.2 FEATURES

The High-Speed PWM module consists of the following major features:

• Up to seven PWM generators, each with an individual time base

• Two PWM outputs per PWM generator

• Individual period and duty cycle for each PWM output

• Duty cycle, dead time, phase shift and frequency resolution equal to the system clock

source (TOSC)

• Independent fault and current-limit inputs for up to 14 PWM outputs

• Redundant Output mode

• Independent Output mode (this feature is not available on all devices)

• Push-Pull Output mode

• Complementary Output mode

• Center-Aligned PWM mode

• Output override control

• Special Event Trigger

• PWM capture feature

• Prescaler for input clock

• ADC triggering with PWM

• Independent PWM frequency, duty cycle and phase shift changes

• Leading-Edge Blanking (LEB) functionality

• Dead time compensation

• Output clock chopping

Note: This family reference manual section is meant to serve as a complement to device

data sheets. Depending on the device variant, this manual section may not apply to

all dsPIC33E/PIC24E devices.

Please consult the note at the beginning of the “High-Speed PWM” chapter in the

current device data sheet to check whether this document supports the device you

are using.
