Reconfigurable matrix-based power distribution architecture

A power management and distribution (PMAD) system includes a first power supply 113 of a first type, a second power supply 118 of a second type different from the first type and first and second loads 121, 122. The PMAD system includes a matrix 130 of solid state power controllers (SSPCs) connected between the first and second power supplies and the first and second loads. The matrix is configured to selectively supply each of the first and second loads with a plurality of different power levels based on on/off states of the SSPCs of the matrix.
