Nowadays, solid-state power controllers (SSPCs) are widely used in aircraft secondary power supplies due to their higher switching cycles, lighter weight, flexible tripping behavior, and fieldbus connections. Usually, they protect the load and its connecting wires. One drawback of these solid-state switches is the typical 28V secondary power supply used for controlling components. We need to develop an effective power supply arrangement that can use onboard power sources as energy sources. Parallel MOSFETs represent switch units. Can be used for self checking without interrupting the power supply connected to the load.
