ABSTRACT: This report documents the development and subsequent fabrication of a solid state auxiliary power conditioning unit for the upgraded Metroliner. The APCU is an inverter of the pulse width modulated type having multiple parallel transistors in a three phase double way bridge configuration. The APCU is packaged to be tested and evaluated in a laboratory environment and proposed to be a prototype of units suitable for replacement of rotary type APU’s presently installed in General Electric power system equipped Metroliners.
