    Abstract: The invention relates to a method in a voltage source chain-link converter (1). The method comprises: detecting (41) a failure of a device (24) of one converter cell module (10, 20,..., n); blocking (42) a phase-leg (A) comprising the failed position (24); discharging (43) to zero a capacitor unit (29) of the converter cell module (20) comprising the failed position (POS4); and providing (44) a current path (30) for the phase current through the converter cell module (20) with the failed position (POS4), the current path (30) comprising a first branch (30), in turn comprising corresponding positions (POS1, POS2) of the first phase-leg (A) and the second phase-leg (B) in the full H-bridge arrangement, the first branch (30) being connected in parallel to a second branch (31) comprising the failed position (POS4), the second branch (31) comprising the remaining two positions (POS3, POS4) of the full H-bridge arrangement. The invention also encompasses corresponding computer program and computer program products.

    Abstract: According to the present disclosure, an evaporating unit (40a) for cooling a heat emitting device (10) is provided. Typically, a cooling circuit (20a) comprises a stack (22) of evaporating units (40a) arranged in alternation with heat emitting devices (10). Each evaporating unit (40a) is connected to a condenser (80) and comprises a first inlet channel (43a), a first plurality of evaporation channels (45a), and a first outlet channel (50a). The evaporating unit (40a) is designed to pre-heat the cooling fluid flowing therein.
