DC Emulator

Overview

The DC Emulator (DCE) is a wideband highly dynamic DC source and load capable of emulating dynamic, complex bidirectional loads for power system and component development and testing. Originally developed for the US Air Force for Hardware in the Loop (HIL) testing to emulate large switching and regenerative loads on aircraft and to study their effect on the power system as a whole, the DCE’s capabilities and flexibility redefine the standard for development and test facility equipment.
