Motor generators have been used as the main method of power conversion and power transfer between the ac system and the dc system on nuclear submarines since the inception of the programme. The developments in the power handling capability of power electronic devices have allowed a static alternative to the rotary motor generator to be adopted. One of the major advantages to be realised by static conversion will be an increase in submarine availability. Additionally, static conversion opens up the possibility of alternative power system architecture and motor control. Static conversion, however, brings with it new challenges to equipment and system designers, including electromagnetic compatibility (emc). Having identified the main sources and effects of electromagnetic interference, equipments/systems are designed to ensure their correct operation in the installation, particularly where they are associated with safety related systems. Converter designs using high power, fast switching devices, introduce potential sources of interference at different frequencies than previously encountered. In addition, the control and power electronics associated with high power switching systems are themselves susceptible to the effects of electromagnetic interference from other sources in the installation. Having designed the equipment, emc verification testing is carried out to demonstrate that the requirements have been met.
