Switch-Mode Power

Average Current Mode Interleaved PFC Control Reference Design

The HVP-KV46F150M – High-Voltage Development Platform Controller Card, Kinetis V MCU, KV46, 150MHz reference solution from NXP describes digital implementation of an interleaved power factor correction (PFC) operating in continuous conduction mode (CCM) using the Kinetis KV46 ARM® Cortex®-M4-based MCU .

The reference manual includes system design concept, software design, control loops design and PFC integration into the target application. The application was developed using the NXP high-voltage development platform. Control loops were designed in MCAT tool. The source code of this reference solution is available.

Features include:

  • Digitally-controlled interleaved PFC
  • Average current control mode
  • 85- to 240-Vac
  • 390Vdc bus output
  • 800W output power
  • 100kHz switching frequency
  • 50kHz current loops
  • 1kHz voltage loop
