| Abstract |
More and all-electric aircraft (AEA) carry many loads with varied functions. In particular, there may be large pulsed loads with short duty ratios which can affect the normal operation of other loads. In this paper, a converter with spilt capacitors and an improved adaptive controller is used as the Voltage Bus Conditioner (VBC) with the reduced capacitive storage to mitigate the voltage transients on the bus. The proposed converter allows the smaller capacitive storage. Also, the proposed controller has the advantage of requiring only one sensor and performing both the functions of mitigating the voltage bus transients and maintaining the level of energy stored. Experimental results are presented which verify the control principles and demonstrate the practicality of the approach. |
