On-demand Webinar | Digitally controlled totem pole PFC with Inrush Current Limitation

Reference design board for a compact, 3.6 kW turnkey power factor corrector...
  

Designing smaller and lighter AC-DC power converters with higher input power factor (PF) and lower harmonic distortion THD is a major challenge for developers who are often pressured by time and budget constraints.
 
We show how you can significantly cut time-to-market by implementing an effective and efficient totem pole PFC solution with highly responsive digital inrush current control, using SiC MOSFETs and SCRs.
  
 
This on-demand webinar demonstrates how our STEVAL-DPSTPFC1 reference board with turnkey bridgeless totem pole boost circuitry can help you meet and exceed today’s efficiency and performance requirements for an AC-DC power factor corrector up to 3.6 kW. 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 on SCR thyristors, SiC MOSFET, isolated drivers and the STM32 microcontroller.
  

Main applications: 

  • High power switched-mode power supplies (SMPS)
  • EV charging stations
  • Motor drives

This webinar will guide you through:  

  • Target applications and markets
  • STEVAL-DPSPFC-1 solution overview
