AC-DC Rectifiers


Excelitas is a recognized industry leader in providing power solutions for the most demanding Defense and industry environments. We provide a full range of AC – DC rectification capabilities and custom solutions:

  • TRU / Lightweight TRU: Multiphase transformer-rectifier units convert three-phase power to bulk DC while reducing line current harmonics to less than 3%. 50/60 Hz versions for naval and ground applications. Lightweight 400/800 Hz versions for airborne applications. Power ratings from 1 kW.
  • 3 Phase Power Factor Correction: An all-electronic alternative to TRUs, providing higher packing density and lighter weight. 5 kW modules may paralleled to provide higher output power.
  • High Power: Very efficient, simple and light-weight rectifiers to converter three-phase input power to bulk DC power. Typically rated 50 kW and up.
  • Off-line Switchers: A full range of switch-mode power supplies ranging from 100 watts to 5000 watts, with or without power factor correction. Topologies used are flyback, forward converter, half-bridge or full bridge, depending on output power. Single or multiple outputs. Fully ruggedized and very high packing density.
  • Custom AC-DC Solutions: Excelitas is happy to review your custom specification and propose an innovative and cost-effective solution. Excelitas excels at high-density packaging in unusual shapes.
