1kW Reference Design Implementing CCM Totem Pole PFC and Current Mode LLC with C2000™ and GaN

Overview

TopologyPower Factor Correction
Input voltage100-264 V
Output 112 V / 84 A
IC revisionV4.1

Description

This reference design demonstrates a hybrid hysteretic control (HHC) method, a current-mode control method, on a half-bridge LLC stage using C2000™ F28004x microcontrollers. The hardware is based on the TIDA-010062 1kW, 80 Plus Titanium Grade, GaN CCM Totem Pole Bridgeless PFC and Half Bridge LLC Reference Design. Hybrid hysteretic control is achieved by additionally adding a proximity card to regenerate the voltage across the resonant capacitor. Compared to the single-loop voltage-mode control method (VMC), this HHC LLC stage has better transient response and easier-to-control loop design.

Features

  • Charge or Current Mode Control LLC
  • 10kHz loop bandwidth
  • Settling time of less than 100µs
  • Deviation less than 500mV under full load conversion
  • Overcurrent and Overvoltage ProtectionFlexible Synchronous Rectification

Typical applications

  • tandalone controller with primary and secondary side control, Server PSU (<= 1kW) with 12V output and digital control
