Power distribution system and method

A direct current (DC) power distribution system, comprising:

• a plurality of power sources;
• a DC power distribution bus comprising a plurality of DC bus sections;
• wherein at least one power source of the plurality of power sources is coupled to each of the DC bus sections;
• one or more power switching assemblies;
• wherein one power switching assembly of the one or more power switching assemblies couples one of the plurality of DC bus sections to another of the plurality of DC bus sections, a system controller to control the plurality of power sources and the one or more power switching assemblies;
• and
• an inverter connected to the one of the one or more power switching assemblies to supply a consumer;
• wherein the one of the one or more power switching assemblies comprises:
• a first terminal and a second terminal, the first terminal being electrically coupled to a first bus section of the DC power distribution bus and the second terminal being electrically coupled to a second bus section of the DC power distribution bus;
• a first semiconductor device and a second semiconductor device electrically coupled between the first terminal and the second terminal to control current flow between the first terminal and the second terminal;
• a current connection from each of the first terminal and the second terminal to a power switching assembly controller for providing an indication of current at the first terminal and at the second terminal;
• a control signal line connected between the power switching assembly controller and each of the first semiconductor device and the second semiconductor device for providing a control signal to the first semiconductor device and the second semiconductor device to control the current flow through them;
• and
• an inverter coupler for coupling the current connection from the first terminal and the current connection from the second terminal to the inverter;
• wherein the inverter coupler comprises a feed from the current connection from the first terminal and the current connection from the second terminal to the inverter.
