Discover a high-efficiency, high-power AC to DC conversion solution with our Vienna 3-phase PFC reference design. Engineered for next-generation systems like EV chargers, industrial power supplies, and data centers, this complete 30 kW front-end solution leverages a proven Vienna rectifier topology and Silicon Carbide (SiC) technology to deliver up to 98.6% efficiency.
⚡ Key Technical Features:
High Efficiency: Up to 98.6% efficiency at full load.
Power Specs: 380–400 VAC three-phase input to a regulated 700 V DC output.
Advanced SiC Power Stage: Utilizes SiC MOSFETs and Schottky diodes at a 140 kHz switching frequency to maximize power density and minimize system size.
Digital Control: Powered by the dsPIC33AK DSC for high-bandwidth control loops and precise grid synchronization.
Robust Protection & Comms: Microsecond-level fault response and integrated CAN FD for real-time diagnostics.
Accelerate your development, reduce design complexity, and meet strict power quality requirements with a fully validated design.
