Capabilities selected rules, recommendations and problems for the design of power electronics equipment installed on ships

The paper presents an analysis of the state and possibilities of using power electronics and electric drives on ships, and in particular, in ship engine room. Problems related to the operation of power electronics in the soft network are presented. The issues related to the design of multi-pulse high power rectifiers are discussed, which is one of the most popular power electronics devices used on vessels. Then a simulation study of selected rectifier circuits was carried out. The purpose of this study was to show the effect of selecting a power electronics design on the waveforms of the voltages and currents in a soft network on the rectifier example. Also discussed are main electromagnetic device problems and issues related to regulations and recommendations for their design and operation. Proper selection of the type of the power supply design and observance of the rules and regulations ensures the efficiency of the equipment and the quality of the energy being processed and reduces their negative impact on the remaining equipment and network.
