The STEVAL-DPSTPFC1 3.6 kW bridgeless totem pole boost circuit achieves a digital power factor correction (PFC) with inrush current limiter (ICL). It helps you to design an innovative topology with the latest ST power kit devices: a silicon carbide MOSFET (SCTW35N65G2V), a thyristor SCR (TN3050H-12WY), an isolated FET driver (STGAP2S) and a 32-bit MCU (STM32F334). This reference design also opens the path to a compact converter running at 72 kHz offering a high peak efficiency, low THD distortion (97.5 % with 3.7 % THD) and reduced bill of materials. It achieves a robust circuit that meets EMC standards up to 4 kV delivering high switching lifetime with reduced EMI emissions. The thyristor SCR used as AC line polarity switcher allows achieving an active current limitation at power up or line drop recovery: the PFC efficiency is optimal and no EMI bouncing effect occurs. The reference design includes a power board with bridgeless totem pole boost (with an inrush limiter circuit, switch drivers and an auxiliary power supply), a control board with its MCU, a PFC/ICL control firmware and an adapter board for software debug. https://elecena.pl/product/17496813/steval-dpstpfc1-3-6-kw-totem-pole-pfc-with-inrush-current-limiter-reference-design-using-tn3050h-12wy-and-sctw35n65g2v 2021-04-05 https://elecena.pl/product/17496813/steval-dpstpfc1-3-6-kw-totem-pole-pfc-with-inrush-current-limiter-reference-design-using-tn3050h-12wy-and-sctw35n65g2v 2021-05-08 https://elecena.pl/product/17496813/steval-dpstpfc1-3-6-kw-totem-pole-pfc-with-inrush-current-limiter-reference-design-using-tn3050h-12wy-and-sctw35n65g2v 2021-06-08 https://elecena.pl/product/17496813/steval-dpstpfc1-3-6-kw-totem-pole-pfc-with-inrush-current-limiter-reference-design-using-tn3050h-12wy-and-sctw35n65g2v 2022-06-10 https://elecena.pl/product/17496813/steval-dpstpfc1-3-6-kw-totem-pole-pfc-with-inrush-current-limiter-reference-design-using-tn3050h-12wy-and-sctw35n65g2v 2022-06-23 https://elecena.pl/product/17496813/steval-dpstpfc1-3-6-kw-totem-pole-pfc-with-inrush-current-limiter-reference-design-using-tn3050h-12wy-and-sctw35n65g2v 2023-03-24 https://elecena.pl/product/17496813/steval-dpstpfc1-3-6-kw-totem-pole-pfc-with-inrush-current-limiter-reference-design-using-tn3050h-12wy-and-sctw35n65g2v 2023-07-16 https://elecena.pl/product/17496813/steval-dpstpfc1-3-6-kw-totem-pole-pfc-with-inrush-current-limiter-reference-design-using-tn3050h-12wy-and-sctw35n65g2v 2024-08-30 https://elecena.pl/product/17496813/steval-dpstpfc1-3-6-kw-totem-pole-pfc-with-inrush-current-limiter-reference-design-using-tn3050h-12wy-and-sctw35n65g2v 2024-09-08 https://elecena.pl/product/17496813/steval-dpstpfc1-3-6-kw-totem-pole-pfc-with-inrush-current-limiter-reference-design-using-tn3050h-12wy-and-sctw35n65g2v 2024-09-17 https://elecena.pl/product/17496813/steval-dpstpfc1-3-6-kw-totem-pole-pfc-with-inrush-current-limiter-reference-design-using-tn3050h-12wy-and-sctw35n65g2v 2024-09-24 https://elecena.pl/product/17496813/steval-dpstpfc1-3-6-kw-totem-pole-pfc-with-inrush-current-limiter-reference-design-using-tn3050h-12wy-and-sctw35n65g2v 2024-10-03 https://elecena.pl/product/17496813/steval-dpstpfc1-3-6-kw-totem-pole-pfc-with-inrush-current-limiter-reference-design-using-tn3050h-12wy-and-sctw35n65g2v 2024-10-21 https://elecena.pl/product/17496813/steval-dpstpfc1-3-6-kw-totem-pole-pfc-with-inrush-current-limiter-reference-design-using-tn3050h-12wy-and-sctw35n65g2v 2024-10-30 https://elecena.pl/product/17496813/steval-dpstpfc1-3-6-kw-totem-pole-pfc-with-inrush-current-limiter-reference-design-using-tn3050h-12wy-and-sctw35n65g2v 2024-11-17 https://elecena.pl/product/17496813/steval-dpstpfc1-3-6-kw-totem-pole-pfc-with-inrush-current-limiter-reference-design-using-tn3050h-12wy-and-sctw35n65g2v 2024-12-05 https://elecena.pl/product/17496813/steval-dpstpfc1-3-6-kw-totem-pole-pfc-with-inrush-current-limiter-reference-design-using-tn3050h-12wy-and-sctw35n65g2v 2025-02-07 https://elecena.pl/product/17496813/steval-dpstpfc1-3-6-kw-totem-pole-pfc-with-inrush-current-limiter-reference-design-using-tn3050h-12wy-and-sctw35n65g2v 2026-02-24 https://elecena.pl/product/17496813/steval-dpstpfc1-3-6-kw-totem-pole-pfc-with-inrush-current-limiter-reference-design-using-tn3050h-12wy-and-sctw35n65g2v 2026-03-06 https://elecena.pl/product/17496813/steval-dpstpfc1-3-6-kw-totem-pole-pfc-with-inrush-current-limiter-reference-design-using-tn3050h-12wy-and-sctw35n65g2v 2026-03-25 https://elecena.pl/product/17496813/steval-dpstpfc1-3-6-kw-totem-pole-pfc-with-inrush-current-limiter-reference-design-using-tn3050h-12wy-and-sctw35n65g2v 2026-04-03 https://elecena.pl/product/17496813/steval-dpstpfc1-3-6-kw-totem-pole-pfc-with-inrush-current-limiter-reference-design-using-tn3050h-12wy-and-sctw35n65g2v 2026-04-22 https://elecena.pl/product/17496813/steval-dpstpfc1-3-6-kw-totem-pole-pfc-with-inrush-current-limiter-reference-design-using-tn3050h-12wy-and-sctw35n65g2v 2026-05-30 https://elecena.pl/product/17496813/steval-dpstpfc1-3-6-kw-totem-pole-pfc-with-inrush-current-limiter-reference-design-using-tn3050h-12wy-and-sctw35n65g2v 2026-08-05
