Abstract
An electrical cabinet including a high-power converter. The high-power converter includes at least three power modules, at least one reactor, and a cooling system configured for cooling the at least three power modules and the at least one reactor. A plurality of high-power electrical conductors establish a three-phased current path from a power inlet of the electrical cabinet via the at least three power modules and the at least one reactor to a power outlet of the electrical cabinet. At least one of the high-power electrical conductors is manufactured at least partly by an additive manufacturing process.
Claims28
A three-phased high-power converter comprised by an electrical cabinet, said high-power converter comprising:
- at least three power modules;
- at least one reactor;
- a cooling system configured for cooling said at least three power modules and said at least one reactor;
- and
- a plurality of high-power electrical conductors establishing a three-phased current path from a power inlet of said electrical cabinet via said at least three power modules, and via said at least one reactor to a power outlet of said electrical cabinet,
- wherein at least one of said high-power electrical conductors is a transition busbar manufactured at least partly by an additive manufacturing process to obtain a geometry that is multifunctional with a non-massive core,
- wherein said non-massive core is provided as an open channel inside said transition busbar with airgaps in an outer perimeter of the transition busbar configured for allowing an air flow through the interior of said transition busbar, and
- wherein said transition busbar is multifunctional in that, in additional to conduct current, said airflow passing through the interior of the transition busbar, is configured to temperature regulate said transition busbar.
