Variable-frequency, ZVS, 5-kW, GaN-based, two-phase totem-pole PFC reference design

Overview

TopologyPower Factor Correction
Input voltage120-277 V
Output 1400 V / 12.5 A

Description

This reference design is a high-density and high-efficiency 5-kW totem-pole power factor correction (PFC) design. The design uses a two-phase totem-pole PFC operating with variable frequency and zero voltage switching (ZVS). The control uses a new topology and improved triangular current mode (iTCM) to achieve both small size and high efficiency. The design uses a high performance processing core inside a TMS320F280049C microcontroller to maintain efficiency over a wide operating range. The PFC operates with variable frequency between 100 kHz and 800 kHz. A peak system efficiency of 99% was achieved with an open-frame power density of 120 W/in3.

Features

  • 99% efficient
  • 120 W/in3 power density
  • 5-kW and 20-ms hold up
  • 180 W/in3 power density without hold up
  • Phase shedding

Typical applications

  • EV charging station power module
  • Merchant network & server PSU, Merchant telecom rectifiers
  • Medium/short range radar
  • Solar power optimizer
  • DC-input BLDC motor drive, Industrial AC-DC
  • Energy storage power conversion system (PCS)
