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 75 kHz offering a high efficiency at full load (97.5%) and a low THD distortion (5 % max. at 10 % of maximum load).
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 bridgeless totem pole boost, an inrush limiter circuit, switch drivers, an auxiliary power supply, a control board with its MCU, a PFC/ICL control firmware and an adapter board for software debug.主要特性
