This 60 to 400Hz 90KVA DSP controlled, IGBT based frequency converter is used for aircraft
ground support of Army helicopters. The input is selectable
480V/220V/380V, 50/60Hz and thus can be used globally. The unit is
equipped with two outputs to enable powering two aircraft simultaneously.
This project utilizes the same inverter technology as the proposed effort,
is used for aircraft ground support, and is similar in design complexity.
There are a number of specification similarities including required
conformance to MIL-STD-704F. This unit is UL 1012 compliant |
