Three-Phase AC-DC Converters and Active Power Factor Correction

Electronic three-phase AC-DC converters with active power factor conversion for the conversion of 115VAC aircraft, naval and 208VAC ground power to 365VDC nominal. The all-electric alternative to our TRUs and ATRUs, our three-phase APFC solutions provide higher packing density and lighter weight for avionics, aircraft systems, naval and land based systems.

Our front-end power factor correction (PFC) modules can be used stand-alone or to supply regulated voltage to DC-DC converters. 

The PFC module can be analog or digitally controlled and provides power factors near 1.0 with very low harmonic distortion, which will meet commercial and military specifications. 

Key Features: 

  • 115VAC 50/60 Hz and 360 to 800 Hz input
  • 5kW output, modules may be paralleled to provide higher output power
  • High power density >150W/in3
  • Companion EMI filter
  • Digital control and telemetry
  • Tolerant to phase loss
  • Protection circuits including OVP and over-temperature

Electrical Performance: 

  • Power Factor > .99
  • Designed to meet DO-160G and MIL-STD-1399 Section 300 harmonics
  • Up to 97% efficiency

TRUs and ATRUs

We design and manufacture multi-phase transformer rectifier units and lightweight auto-transformer rectifier units suitable for airborne and shipboard applications. 

TRUs are a high reliability solution for applications requiring reduction of input line current harmonics, such as avionics and aircraft systems, as well as military shipboard electronics.
