Abstract: A method and a control system adapted to control a power conversion system connected to an AC power grid, wherein the control system is adapted to receive an externally provided reactive power reference and the control system includes a controller adapted to control the reactive power fed to the AC grid by the power conversion system and to produce a reactive current reference, an active current reference, a total current limiter for producing limited active and reactive current references. The total current limiter operates in reactive current priority limiting the active current reference. Further including means adapted to produce a capacity signal indicating the current capacity of the power conversion system. The control system further includes a minimum reactive power reference tracker adapted to generate an internally generated reactive power reference which is adapted to be fed to the controller adapted to control the reactive power fed by the power conversion system to the AC grid, where the minimum reactive power reference tracker is adapted to control the internally generated reactive power reference to a value with which the active current reference is not limited.

Abstract: An electrical multi-phase converter and method for controlling an electrical multi-phase converter is disclosed. In one form a method provides for controlling the electrical multi-phase converter comprises: determining at least two supply voltages for the at least two converter cells of the at least two phase branches; determining a potential zone for each phase branch based on the at least one supply voltage of the at least one converter cell of the phase branch, the potential zone bounding a possible actual phase voltage producible by the phase branch; receiving a reference voltage for each phase branch; and, if the reference voltage for a phase branch is not within the potential zone of the phase branch, setting the reference voltage to a bound of the potential zone and shifting reference voltages of other phase branches, wherein the reference voltages are set and shifted such that a minimal common mode voltage between the output voltages of the multi-phase converter is generated.

Abstract: The invention relates to a cooling element (11) comprising: a fluid channel (1) providing a pulsating heat pipe, a first evaporator (14) for receiving heat from electric components (15) and for passing the heat into fluid in the fluid channel (1), and a first condenser (18) for receiving fluid from the first evaporator (14) via the fluid channel (1) and for cooling fluid in the fluid channel. In order to obtain an even temperature distribution at the first evaporator (14) an adiabatic zone where the temperature of the fluid in the fluid channel (1) remains unchanged or a cooling zone, with a second condenser (20) cooling fluid in the fluid channel (1), separates the first evaporator (14) from the loops (6) in the second end (12) of the fluid channel.
