STEVAL-DPSTPFC1

STEVAL-DPSTPFC1 Reference Design

STMicroelectronics STEVAL-DPSTPFC1 Reference Design is a 3.6kW bridgeless totem pole boost circuit that implements a digital power factor correction (PFC) with an inrush current limiter (ICL). The STEVAL-DPSTPFC1 Design also opens the path to a compact converter running at 72kHz, offering a high peak efficiency, low THD distortion (97.5% with 3.7% THD), and reduced bill of materials. The STEVAL-DPSTPFC1 employs a robust circuit that meets EMC standards up to 4kV, delivering a high switching lifetime with reduced EMI emissions. The thyristor SCR used as an AC line polarity switcher enables an active current limitation at power-up or line drop recovery. The PFC efficiency is optimal, and no EMI bouncing effect occurs.
