FIELD: cooling systems.;SUBSTANCE: invention relates to a cooling system for a power converter, to a power converter with such a cooling system, as well as to a method for regulating and/or controlling such a cooling system or such power converter. Cooling system (1) for power converter (2) contains first (11) and second (12) cooling channels located at least in parallel. Moreover, in the area of parallel arrangement, first cooling channel (11) is made for cooling semiconductors (21) of power converter (2), second cooling channel (12) is made for cooling capacitors (22) of the intermediate circuit of power converter (2), and both are made as air channels. Cooling system (1) includes an air distributor for distributing the airflow between first cooling channel (11) and second cooling channel (12) in a ratio ranging from 80:20 to 95:5.;EFFECT: technical result is maintenance of the permissible maximum temperature of the environment for the intermediate circuit capacitors, while simultaneously removing the higher power of the heat losses of the power semiconductors, which prevents components failure.;6 cl, 2 dwg
