Description

Interleaved Continuous Conduction Mode (CCM) Totem Pole (TTPL) Bridgeless Power Factor Correction (PFC) is an attractive power topology with use of high band-gap GaN devices, because of high efficiency and reduced size of the power supply. This design illustrates a method to control this power stage using C2000™ MCUs and the LMG3410 GaN FET module. Adaptive dead-time & phase shedding methods are implemented for improved efficiency.  The Non- Linear Voltage Compensator is designed to  reduce overshoot and undershoot during transients. A software phase locked loop(SPLL) based scheme is chosen to drive the totem pole bridge accurately. The hardware and software available with this design helps accelerate your time to market.

Features
  • AC Input (90-230Vrms), 50-60Hz and 3.3KW rated power at high line
  • 98.75% peak efficiency and less than 2% Total Harmonic Distortion (THD)
  • powerSUITE support for easy adaptation of the design for user requirement
  • In built frequency response analyzer (SFRA) for verification and design of control loops
  • Low zero crossing distrotion
  • Illustrates Adaptive dead-time, Phase Shedding and Non Linear Voltage Compensator implementation
  • Control of the power stage can run on the C28x CPU or the parallel CLA
