Description

The STDES-30KWVRECT reference design introduces a complete digital power solution for high-power threephase active front end (AFE) rectifier applications based on the three-level Vienna topology. This platform achieves a peak efficiency of more than 98.5% by using the SCTWA90N65G2V-4 and the STPSC40H12CWL.It features a fully digital control with the STM32G474RET3 mixed-signal high-performance microcontroller, providing the full control of the PF, DC voltage, and soft startup procedure. The STDES-30KWVRECT achieves a low total harmonic distortion (less than 5% THD at full load) and a high power factor (higher than 0.99 at full load), providing a high-bandwidth continuous conduction mode (CCM) current regulation. The STDES-30KWVRECT is a fully assembled kit developed for performance evaluation only, not available for sale.

Features

  • Three-phase, three-level AC-DC power converter:
  • Nominal rate for DC voltage: 800 VDC
  • Nominal rate for AC voltage: 400 VAC at 50 Hz
  • Maximum power: 30 kW
  • Power factor: >0.99
  • Inrush current control and soft start-up
  • THD lower than 5% at nominal operation
  • Power section based on SiC MOSFETs and SiC diodes:
  • High frequency operation (70 kHz)
  • High efficiency: >98.5%
  • Paralleled SiC MOSFETs for higher power with balanced sharing current
