1. A primary power switching network system comprising:
- a plurality of primary power switching buses configured for distributing primary power to a plurality of modular equipment centers (MECs); and
at least one standalone solid state switch on the primary power switch network system, the at least one standalone solid state switch having a self-contained control function configured to provide one or more of localized protections, voltage sensing, and current sensing, and wherein opening and closing of the at least one standalone solid state switch interrupts and routes primary power across one or more of the primary power switching buses to one or more of the plurality of MECs, wherein the standalone solid state switch comprises pulse width modulation to limit current flow through the standalone solid state switch.

Abstract
A solid state primary power switching network for modular equipment centers (MECs) distributing primary power throughout a vehicle. The solid state primary power switching network includes multiple primary power switch network devices (PPSNDs) of a MEC for controlling and distributing primary power to other MECs spatially distribute throughout a vehicle. In one or more configurations, the PPSNDs have a universal structure in that each includes a common power input source and a plurality of common power outputs. In one or more configurations, primary power sources to the vehicle are switched without a perceivably visible break in power.

2. A fast break power transfer system for switching between primary power sources to a vehicle, the fast break power transfer system comprising:
-
the primary power sources having different output frequencies configured to provide high voltage AC power inputs to a high voltage primary power bus; a static inverter configured for receiving a DC input; and a first solid state power breaker (SSPB) between the static inverter and a backup bus coupled to the high voltage primary power bus, wherein the static inverter is further configured to sync to the output frequency and phasing of one of the primary power sources powering the high voltage primary power bus and the first SSPB is configured to provide a controlled frequency output and a voltage from the static inverter to the backup bus such that the high voltage primary power bus remains continuously powered during a power transfer to another of the primary power sources available for powering the high voltage primary power bus. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15)

16. A method for switching between primary power sources to a vehicle, the method comprising:
-
providing first and second primary power sources having different output frequencies; providing a high voltage AC power input to a high voltage primary power bus from the first primary power source; synchronizing a static inverter to an output frequency of the first primary power source powering the high voltage primary power bus; interrupting the high voltage AC power input from the first primary power source to the high voltage primary power bus; in response to interrupting the high voltage AC power input from the first primary power source, providing a controlled frequency output and a voltage from the static inverter to a backup bus coupled to the high voltage primary power bus; powering the high voltage primary power bus from the backup bus until the second primary power source powers the high voltage primary power bus; changing the output frequency of the static inverter to match an output frequency of the second primary power source; taking the static inverter offline upon an occurrence of matching output frequencies; and powering the high voltage primary power bus from the second primary power source. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25)
