High efficiency 3-phase PFC with SiC & digital control

ST brings together its comprehensive know-how and experience in power conversion and energy management to present several front end reference designs for industrial high power conversion applications, including charging stations, high power OBCs and electric motor drives.

Our designs are based on high frequency SiC MOSFETs and SiC Diodes, with inherent material properties that raise the bar in terms of efficiency and performance, and precision control options ranging from high performance mixed-signal analog/digital ICs to fully digital solutions leveraging the power and flexibility of the STM32F3x4 microcontroller.
