An exemplary evaporating unit for cooling a heat emitting device includes a cooling circuit having a stack of evaporating units arranged alternately with heat emitting devices. Each evaporating unit is connected to a condenser and includes a first inlet channel, a first plurality of evaporation channels, and a first outlet channel. The evaporating unit is designed for pre-heating the cooling fluid flowing therein.

Power electronics cooling

An exemplary modular cooling system for cooling a plurality of electronic components is provided. The cooling system includes a plurality of cooling modules and a clamping arrangement. Each cooling module includes an evaporator unit, a condenser, a first pipe system, and a second pipe system. The clamping arrangement is adapted for holding and pressing an alternation stack in which the evaporator units are stacked in alternation with the power electronic components.

Modular cooling system

A method in a voltage source chain-link converter. The method includes: detecting a failure of a device of one converter cell module; blocking a phase-leg including the failed position; discharging to zero a capacitor unit of the converter cell module including the failed position; and providing a current path for the phase current through the converter cell module with the failed position, the current path including a first branch, in turn including corresponding positions of the first phase-leg and the second phase-leg in the full H-bridge arrangement, the first branch being connected in parallel to a second branch including the failed position, the second branch including the remaining two positions of the full H-bridge arrangement. The invention also encompasses corresponding computer program and computer program products.
