Three-phase Vienna rectifier

Three-phase power is often used by high power industrial applications. To improve overall quality and minimize harmonic currents power factor correction (PFC) is often required as many of the forward loads are DC – for example electric vehicle (EV) battery charging. The Vienna rectifier power topology is often the preferred choice as it operates in continuous conduction mode (CCM), has inherent multilevel switching (three level), and reduced voltage stress on the power devices.

Design challenges

  • Primary side converter devices could be MOSFETs (depending on voltage output), to be more cost effective. Alternatively they should be GaN FETs for greater efficiency and lower switching losses.
  • Lower thermal dissipation
  • Input switches can be GaN, SiC or IGBT devices (if IGBT, requires a parallel diode)

MOSFET and GaN FET Handbook

Drawing on over 20 years’ of experience, the MOSFET and GaN FET Application Handbook: A Power Design Engineer’s Guide brings together a comprehensive set of learning and reference materials relating to the use of MOSFETs and GaN FETs in real world systems.
