17 High-Resolution Pulse-Width Modulation (PWM)

This section describes the use of the High-Resolution Pulse-Width Modulation (PWM) in the PIC32AK1216GC41064 family of devices. This flexible module provides features to support many types of Motor Control (MC) and Power Control (PC) applications, including:

  • AC-to-DC Converters
  • DC-to-DC Converters
  • AC and DC Motor Control: Brushed DC, BLDC, PMSM, ACIM, SRM, Stepper, etc.
  • Inverters
  • Battery Chargers
  • Digital Lighting
  • Power Factor Correction (PFC)
  • Four Independent PWM Generators, each with Dual Outputs
  • Operating modes:
    • Independent Edge PWM mode
    • Variable Phase PWM mode
    • Independent Edge PWM mode, Dual Output
    • Center-Aligned PWM mode
    • Double Update Center-Aligned PWM mode
    • Dual Edge Center-Aligned PWM mode
  • Output modes: Complementary, Independent, Push-Pull
  • Dead-Time Generator
  • Dead-Time Compensation
  • Leading-Edge Blanking (LEB)
  • Output Override for Fault Handling
  • Flexible Period/Duty Cycle Updating Options
  • PWM Control Inputs (PCI) for PWM Pin Overrides and External PWM Synchronization
  • Advanced Triggering Options
  • Combinatorial Logic Output
  • PWM Event Outputs
