Product overview
Description
The STSW-30KWVRECT firmware package demonstrates the capability of the STDES-30KWVRECT Vienna PFC rectifier reference design to meet high-performance requirements.
A digital solution by the STM32G474RE digital power MCU is used for the Vienna PFC.
The STDES-30KWVRECT reference design topology is mostly used for industrial and electric vehicle DC fast charging applications.
Thanks to the full digitalization and to dedicated control algorithms, the STDES-30KWVRECT achieves a low THD distortion, which is less than 5% at full load, and a high overall efficiency and power factor.
