Maximize Efficiency with a Cost-Effective Silicon-Based Vienna Rectifier Solution

White Paper Overview  

The growing demand for public DC-charging infrastructure requires power conversion systems that are not only highly efficient, but also compliant with international grid codes. The Vienna rectifier has emerged as a widely adopted solution, balancing efficiency with circuit simplicity.  

This white paper explores an innovative approach to integrating a 3-level Vienna rectifier phase-leg into the compact Littelfuse ISOPLUS® SMPD package. It presents a detailed analysis of the prototype design, dynamic switching performance, and loss estimation to demonstrate how silicon-based technology can achieve impressive efficiency without the need for wide band-gap devices like SiC or GaN. The findings offer valuable insights for design engineers and system architects looking to optimize power electronics for EV charging and other grid-connected applications.
