Introduction

The STEVAL-DPSTPFC1 from STMicroelectronics is a high-performance reference design board tailored for advanced power conversion needs. With a focus on efficiency and compactness, this board is engineered to deliver robust power factor correction (PFC) and inrush current limiting for demanding applications.

Part Description

The STEVAL-DPSTPFC1 is a 3.6 kW bridgeless totem pole boost circuit reference design. It incorporates digital power factor correction (PFC) and an inrush current limiter, ensuring both high efficiency and protection during power-up. The design leverages advanced ST components, including a silicon carbide (SiC) MOSFET for fast switching and low losses, a silicon-controlled rectifier (SCR), an isolated FET driver, and a 32-bit microcontroller unit (MCU) for precise digital control. This combination results in low total harmonic distortion (THD) and compliance with electromagnetic compatibility (EMC) standards, making it suitable for modern, compact, and high-performance power conversion systems.
