Abstract
A power semiconductor component with power semiconductor modules connected to a cooling structure, and a cooling chamber having an inlet and outlet port, and adapted for a flow direction of a coolant substance from the inlet port to the outlet port, each of the cooling structures provided within the cooling chamber consecutively in the flow direction forming a flow resistance region in the cooling chamber, the cooling chamber comprises a bypass region connected in parallel to at least one of the flow resistance regions being closer to the inlet port, and is adapted for a flow rate of the at least one flow resistance region, which is connected in parallel to the bypass region, closer to the inlet port being smaller than a flow rate of one of the at least two flow resistance regions closer to the outlet port.
