Product overview

Description

This reference design represents a complete solution for three-phase AC/DC and DC/AC (800 VDC to 400 VAC) applications based on a digital platform optimized for power conversion.

STDES-PFCBIDIR IMAGE

It is well suited for the Active Front End (AFE) stage in high power charging stations, industrial battery chargers and UPS. The high switching frequency of the SiC MOSFETs and the multilevel structure allow nearly 99% efficiency as well as the optimization of passive power components in terms of size and cost.

The STDES-PFCBIDIR is a fully assembled kit developed for performance evaluation only, not available for sale.
