Abstract
An electrical power distribution system (EPDS) for an aircraft, the EPDS may include a DC bus, a power source port, a solid state power controller (SSPC) of a first type interposed between the power source port and the DC bus, at least one load port and an SSPC of a second type interposed between the load port and the DC bus. Power input to the SSPC of the first type may be connected to a unidirectional solid state switching device (SSSD) of the SSPC of the first type. The SSPC of the first type may have forward and reverse current conducting capability and forward and reverse current blocking capability. Power input to the SSPC of the second type may be connected to a unidirectional SSSD of the SSPC of the second type. The SSPC of the second type may have forward and reverse current conducting capability and capability of blocking current from only one direction.
