Claim:
1. Power switching assembly for switching power in a power distribution bus, the power switching assembly comprising: a first terminal; a second terminal; a first semiconductor element and a second semiconductor element electrically coupled between the first terminal and the second terminal, wherein the first semiconductor element coupled between the first terminal and the second terminal is controllable to selectively allow a current flow in a first direction from the first terminal to the second terminal, and wherein the second semiconductor element coupled between the first terminal and the second terminal is controllable to selectively allow a current flow in a second direction, opposite the first direction, from the second terminal to the first terminal; a current sensor for sensing a current flowing between the first terminal and the second terminal and providing a current signal in response hereto; a controller being configured for receiving the current signal and controlling in response hereto the first semiconductor element and the second semiconductor element; wherein the first terminal of the power switching assembly is electrically coupled to a first bus section of the power distribution bus and the second terminal of the power switching assembly is electrically coupled to a second bus section of the power distribution bus; wherein a first generator is electrically coupled to the first bus section independent of the first and second semiconductor elements for providing electrical energy to the first bus section and selectively electrically coupled to the second bus section as a function of the control of the first semiconductor element by the controller; wherein a second generator is electrically coupled to the second bus section independent of the first and second semiconductor elements for providing electrical energy to the second bus section while the first generator is providing electrical energy to the first bus section, and selectively electrically coupled to the first bus section as a function of the control of the second semiconductor element by the controller; wherein each bus section is adapted to electrically couple to at least one electrical consumer; and wherein the controller is configured to perform a load balancing between the first and second generators, with respect to a total load including at least one electrical consumer coupled to the first bus section and at least one electrical consumer coupled to the second bus section, at least by controlling the first semiconductor element and the second semiconductor element to connect and disconnect the first bus section to or from the second bus section.
