Three-Phase Bridges - AC Bridge Rectifiers

Littelfuse subsidiary IXYS makes three types of MOSFET modules that serve as bridge rectifiers and power factor correction circuits. Each module consists of a metal-oxide–semiconductor field effect transistor and a fast recovery diode. One of the modules also includes an IGBT with non-punch through architecture that ensures a large reverse bias safety operating area (RBSOA). The modules frequently get used as solid state ac switches and ac–dc converters in welding machines, switched-mode power supplies, and uninterruptible power supplies.
