1. A pulse inverter comprising:
a plurality of power modules;
at least one capacitor assembly with a plurality of capacitors;
at least one power module cooling channel configured to be perfused by a cooling fluid in order to cool the power modules;
at least one capacitor cooling channel configured to be perfused by the cooling fluid in order to cool the capacitors; and
a plurality of connection channels extending between the at least one power module cooling channel and the at least one capacitor cooling channel, the connection channels being configured to be perfused by the cooling fluid.
