摘要： A circuit for measuring the current distribution in the case of parallel-operating alternating-voltage sources, in which each alternating-voltage source is provided with a current transformer and a first resistor connected to an output terminal thereof. The other output terminal of the first resistor is connected to a circuit point which is common for all the alternating-voltage sources. The output terminals, not connected to the first resistor, of the current transformers of the alternating-voltage sources are connected to one another and to one side of a parallel circuit of a number of second resistors. This number corresponds to the number of parallel-operating alternating-voltage sources. The current delivered by an alternating-voltage source is fed to the input of the current transformer associated therewith, as a result of which the sum of the two terminal voltages of each current transformer is a measure of the current which the alternating-voltage source associated therewith delivers, this being more or less than a predetermined share of the total load current.

摘要： A device for load-sharing parallel connection of alternating-voltage sources to a parallel rail. Each alternating-voltage source is provided with an amplitude-control and frequency-control device and a control circuit for generating control variables and supplying them to the amplitude-control and frequency-control device. The control circuit is provided with means of determining the active and reactive differential power which is delivered by the respective alternating-voltage source above or below a part, associated thereto, of the total active or reactive power, respectively, to be delivered to the parallel rail. Said means derive a frequency-dependent frequency-control variable from the active differential power by means of an integrator and a frequency-dependent amplitude-control variable from the reactive differential power. The frequency-control variable is supplied to the frequency-control section and the amplitude-control variable to the amplitude-control section of the amplitude-control and frequency-control device.
As a result of this control procedure, both the active and reactive powers are proportionally distributed over the alternating-voltage sources, even if these have different control strategies (some synchronise and others do not), without the sources knowing one another's control strategy.

摘要： Symmetrical electrical snubber circuit for protecting at least two series-connected switch members (S₁; S₂) against excessive voltage and current increase during switching. The voltage increase over each of said switch members is limited by a series circuit of a capacitor and an element having diode action (D₁, C₁; D₂, D₂) connected in parallel with said switch members. The magnitude of the DC supply voltage is effectively limited by a further series circuit of a capactior and an element having diode action (D₃, C₃; D₄, C₄) connected with said switch members. A freewheeling diode (D₅, D₆) is connected in parallel with each of said switch members. By incorporating a coil (L₁, L₂) in the supply lines to the switch members, the current increase during switching-on of a switch member is limited. Like this, a symmetrical snubber circuit which is as low in stray inductance as possible is obtained. The energy stored in the coils (L₁, L₂) as well as the energy stored in the capacitors (C₁; C₂) being transferred to the further capacitors (C₃; C₄) due to resonant action. The energy in these further capacitors can then be discharged with the aid of energy transport means (ET). The snubber circuit according to the invention is in essence loss-free.
