Join us for 1-hour webinar to discover how the STEVAL-DPSTPFC1 delivers a compact and turnkey power factor corrector up to 3.6kW   This webinar was broadcasted Tuesday, June 8th 2021   Watch now

AC-DC power converter designers continue to pursue higher input power factor (PF) and lower harmonic distortion THD with increasingly smaller and lighter systems, while they are given less development time to finalize their projects, including fine-tuning converter performance.

During this one-hour webinar, you will see how the STEVAL-DPSTPFC1 reference board helps designers meet the challenges of a modern AC-DC power factor corrector up to 3.6 kW with a turnkey bridgeless totem pole boost circuit. This digitally controlled bridgeless totem pole PFC with inrush current limitation delivers 97.5% full system peak efficiency and CISPR 5022 EMI compliance in a robust (4 kV surge voltage tolerance) and compact design based primarily on SCR thyristors, SiC MOSFET, isolated drivers and the STM32 MCU.

Agenda

• Target applications and markets
• STEVAL-DPSPFC-1 solution overview
• Totem pole topology operation
• Inrush current limitation with SCR
• STEVAL-DPSPFC-1 reference design performance
• Key power products
  • SiC MOSFET
  • Isolated Gate Drivers STGAP
  • SCR
  • Auxiliary SMPS – Viper family

After the webinar, there will be a 15-minute Q&A session where our experts will be available to answer any questions.
