1.0 INTRODUCTION

This section describes the High-Speed PWM module and its associated operational modes. The

High-Speed PWM module supports a wide variety of PWM modes and is ideal for power

conversion applications. Some of the common applications that the High-Speed PWM module

supports are:

• AC-to-DC Converters

• Power Factor Correction (PFC)

• Interleaved Power Factor Correction (IPFC)

• Inverters

• DC-to-DC Converters

• Battery Chargers

• Digital Lighting

• Uninterruptable Power Supply (UPS)

• AC and DC Motors

• Resonant Converters

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 dsPIC33/PIC24 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.

Device data sheets and family reference manual sections are available for download

from the Microchip Worldwide Web site at: http://www.microchip.com.

High-Speed PWM Module

2.0 FEATURES

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

• Up to Nine PWM Generators

• Two PWM Outputs per PWM Generator

• Individual Time Base and Duty Cycle Control for Each PWM Output

• Duty Cycle, Dead Time, Phase Shift and a Frequency Resolution of 1.04 ns

• Independent Fault and Current-Limit Inputs for All PWM Outputs

• Redundant Output

• True Independent Output

• Center-Aligned PWM mode

• Output Override Control

• Special Event Trigger

• Prescaler for Input Clock

• Dual Trigger to Analog-to-Digital Converter (ADC) per PWM Period

• PWM

L and PWM

H Output Pin Swapping

• Independent PWM Frequency, Duty Cycle and Phase-shift Changes

• Leading-Edge Blanking (LEB) Functionality

• PWM Capture Functionality

• Up to Two Master Time Bases

• Dead-Time Compensation

• PWM Chopping

• Support for Class B Protection of Fault Control Registers

Note: Duty cycle, dead time, phase shift and frequency resolution is 8.32 ns in Center-Aligned

PWM mode.

•LEBDLYx: PWMx Leading-Edge Blanking Delay Register

- Specifies the blanking time for the selected Fault input and current-limit signals

•AUXCONx: PWMx Auxiliary Control Register

- Enables or disables the high-resolution PWM period and the duty cycle in order to

reduce the system power consumption

- Selects the state blanking signal for the current-limit signals and the Fault inputs

•PWMCAPx: PWMx Primary Time Base Capture Register

- Provides the captured Independent Time Base value when a leading-edge is detected

on the current-limit input

•PWMKEY: PWMx Protection Lock/Unlock Key Register

- Enables write protection of the PWMx Fault Control registers, IOCONx and FCLCONx,

for providing Class B Fault protection

bit 3-0 SEVTPS<3:0>: PWM Special Event Trigger Output Postscaler Select bits

( )1

1111 = 1:16 Postscaler generates Special Event Trigger on every sixteenth compare match event

•

0001 = 1:2 Postscaler generates Special Event Trigger on every second compare match event

0000 = 1:1 Postscaler generates Special Event Trigger on every compare match event

Note 1: These bits should be changed only when PTEN = 0.

2: The PWM time base synchronization must only be used in the master time base with no phase shifting.

3: When the PWM module is enabled by setting PTCON<15> = 1, a delay will be observed before the PWM

outputs start switching. This delay is equal to:

PWM Turn-on Delay = (2/ACLK) + (3  (PCLKDIV<2:0> Setting)/ACLK) + 15 ns
