Opis:: The paper presents the background and results of numerical simulation and experimental research of a system using auctioneering diodes used to distribute the power of direct current between two power converters operating in parallel. Non-isolated power distribution systems using blocking diodes are used in the ship's electrical power systems, however, they create problems related to control and the possibility of ground faults. Another issue occurring during the operation of this type of systems is the increased heat dissipation. Selected problems related to the operation of the above systems have been identified by means of simulation studies and experiments carried out in a 11 kVA laboratory system and the theoretical basis along with results are provided in the article.

Opis:: The paper covers the theoretical background and tests of two asynchronous squirrel cage generators connected to voltage source inverters working in parallel. Inverters were connected in parallel by their intermediate direct current circuits by means of auctioneering diodes, and then to a DC power network. The real-time control algorithm of digital signal processor DSP and field-programmable gate array FPGA was used to achieve proper excitation of two different power machines, and to maintain high enough levels of direct current link voltage. Windings of both generators are fed by use of so-called machine side inverters. The asynchronous generator is a voltage source inverter controlled by a field-oriented control algorithm based on the current machine model. To prove robustness of the chosen algorithm, different types of load were applied while generators and inverters worked in parallel.
