Case study: Fixed-winged HALE UAV
An upgrade to a high-altitude long endurance (HALE) UAV platform included fitting a new, higher-resolution, longer-range radar and improving the telemetry. The upgrade effectively doubled the power required on the 28V internal bus to 11kW. Onboard power was from two separate power sources for redundancy. The key goals were to:
The small size, low profile and low weight of the Vicor DCM DC-DC converters, module enabled the supply output power to be doubled without exceeding allocated space constraints. The high efficiency (96%) reduced the size of the heat sink required, saving more space. Key benefits were:
Three arrays of three 1.3kW DCM5614 VIA converters were paralleled to provide the regulated 28V bus. Inputs were split between two different generators to provide redundancy of power source. The arrays automatically power shared across all nine converters —though their input voltages differed — helping improve system reliability.
