Abstract
Aviation static converter is an important part of aircraft emergency power supply system which convert DC voltage to 115 V/400 Hz AC voltage when the main power supply fails. High reliability is the primary requirement of aviation static converters. To ensure that converter operates normally under extreme conditions, the power devices should be selected carefully; To avoid electromagnetic attack on the converter operation, some scenario requires that the control system should adopt analog control and the control loop should have a current limiting ability, which further increase the design difficulty of the analog control circuit. This paper proposes the selection method of power switch and inductor core under overload conditions, and proposes a control scheme to realize current limiting in analog control.
