1.6 Digitally Controlled Interleaved LLC Resonant Converter: TIDM-1001

설명

2017년 4월 14일

This presentation provides details of a digitally-controlled 500W two-phase interleaved LLC resonant converter TI design: TIDM-1001. This converter is controlled by a single, C2000 microcontroller (MCU), which generates PWM switching waveforms under all operating modes and implements a new current sharing technique to accurately achieve current balancing between phases. Features:

  • Digitally controlled two phase interleaved LLC resonant DC-to-DC converter
  • Excellent current sharing between phases without any additional hardware
  • Peak efficiency: 94.5%. Efficiency > 90% for all loads above 10% of rated load
  • powerSUITE support for easy adaptation of software for a customized power level
  • Fault protection: phase/output over-current, output over-voltage, and input under-voltage and overvoltage
  • Phase shedding with programmable limits
