Abstract

Nowadays solid-state power controllers (SSPC) are widely used in aircraft secondary power supply, because of a higher count of switching cycles, small weight, flexible trip behavior, and a fieldbus connection. Typically, they protect loads and their connection lines. One drawback of these solid-state switches is the typical 28V secondary power supply for the control elements. This paper shows an effective supply arrangement to use the onboard power supply as energy source. Parallel MOSFETs represent the switching unit. This can be used for a self-test without supply interruption of connected loads. A self-test method is shown in this paper.
