Development of a high-bandwidth active load for an aircraft electrical systems evaluation platform

This paper describes the development of an active load for a 100 kVA, ±270 V dc electrical systems evaluation platform for uninhabited autonomous vehicles, typically airborne. The 30 kW, 3 kHz bandwidth active loads emulate in real time the dynamic behaviour at the dc-bus side of typical aerospace e...

Description
Summary:This paper describes the development of an active load for a 100 kVA, ±270 V dc electrical systems evaluation platform for uninhabited autonomous vehicles, typically airborne. The 30 kW, 3 kHz bandwidth active loads emulate in real time the dynamic behaviour at the dc-bus side of typical aerospace equipment, providing a flexible and cost-effective method of evaluating complex system interactions. This paper, which focuses on the design of the high-bandwidth dc-dc converter, covers the thermal design of the power semiconductors for 20 kHz hard-switching operation, the input and output filter design and the converter modelling and control design. All this is supported by experimental results that validate the design.
