EMC Aspects in Power Conversion Systems for Marine Applications

Given the massive movement towards hybrid power sources and electrification in the marine industry, power conversion systems are increasingly needed to support the flexibility and efficiency required by shipboard electrical grid. Electromagnetic compatibility has been considered as a matter of concern for special ships and for navy designs. The increase in the volume of power electronics systems relative to the installed power onboard the ship brings EMC compliance as a key factor for the good operation of the electrical installation. This paper addresses some EMC aspects that need to be considered in the design and installation of electrical systems incorporating power electronics equipment. Examples are used to highlight some of the solutions for limiting the electromagnetic interference that may occur during the operation of this equipment.
