Performance Evaluation of Silicon-Based 3-Level Vienna Rectifier in ISOPLUS®SMPD Package

Inhalt:
Public DC-charging infrastructure is connected to the public three-phase low-voltage grid. Therefore, it must comply to international standards and the corresponding grid codes. The widely adopted Vienna rectifier allows fulfilling this requirement and offers very high efficiency at low circuit complexity. It allows the use of fast 650 V silicon-based switches and 1200 V diodes. In this paper, measurement results are presented how the Vienna rectifier in the compact ISOPLUS(r) surface mounted power device (SMPD) performs and what power- and efficiency-levels can be achieved based on silicon technology.
