STEVAL-DPSLLCK1 3 kW Power Supply Evaluation Kit
STMicroelectronics' STEVAL-DPSLLCK1 is a digitally controlled 3 kW full bridge LLC resonant DC/DC converter with output synchronous rectification
STMicroelectronics’ STEVAL-DPSLLCK1 reference design provides a 400 V to 48 V, 62.5 A conversion solution built with a modular approach enabling hardware and firmware modularity and portability to accelerate the design of digital SMPS solutions.
The power board implements a full-bridge LLC resonant converter with adaptive output synchronous rectification. The control board hosts the STM32F334R8 microcontroller with firmware uploaded. Both boards are connected through a specifically designed digital power connector to properly interface the power and control stages in the design.
An isolated bidirectional UART is also provided to enable communication with another controller and facilitate the design’s integration into a complete AC/DC digital converter.
