An exemplary power electronics module includes a first power electronics element that generates a first heat flow during operation of the power electronics module, a second power electronics element that generates a second heat flow during operation of the power electronics module. The first cooler is in thermal contact with the first power electronics element to receive at least part of the first heat flow. The second cooler is in thermal contact with the second power electronics element to receive at least part of the second heat flow. A heat exchanger is configured to transmit at least part of the first heat flow and the second heat flow to a primary cooling flow and transfer heat flow in a thermally efficient manner.

An energy generation system includes a turbine, an electric generator, a step-up transformer, and a converter. The turbine is operable to extract energy from a fluid flow and convert the extracted energy into mechanical energy. The electric generator is operable to convert the mechanical energy from the turbine into AC electrical energy. The step-up transformer is operable to transfer the AC electrical energy at a lower voltage from the electric generator to a higher voltage. The converter is operable to convert the AC electrical energy at the higher voltage to DC electrical energy. The converter includes a converter leg for a phase of the AC electrical energy. The converter leg has an upper arm with a first plurality of sub-modules and a lower arm with a second plurality of sub-modules.

The integrated gate dual transistor (IGDT) has two controllable gates (G , G ), a first gate (G ) being provided on the cathode side and being driven via a low-inductance first gate terminal with a first gate current, and a second gate (G ) being provided on the anode side and being driven via a low-inductance second gate terminal with a second gate current. In the switch-off operation of the IGDT, the rate of rise of the voltage across the IGDT is limited via the two gates. Limiting the rate of rise of the voltage across the IGDT prevents voltages from building up at different speeds in a series circuit of IGDTs, and thus unequal loads from overheating and destroying the individual IGDTs.
