“…At present, an increasing number of ships are being equipped with electric propulsion systems powered by a diesel engine, and much less frequently by a package of batteries. Newbuilds with electric high-power main propulsion generally utilize synchronous motors, installed for example in podded propellers [1]. From the power electronic perspective, they are controlled and powered by current and voltage converters.…”

The article presents the results of tests related to failure analysis and finding ways to diagnose used semiconductor elements, among others, in power electronics converter systems on vessels and offshore facilities (drilling and production rigs and wind turbines). Diagnostic relationships were found between the temperature change in the above systems and the signals generated in the form of elastic waves of acoustic emission. The authors confirmed the influence of the transistor’s working temperature on its amplitude-frequency spectrum of acoustic emission signals emitted. The range of ‘safe temperatures’ was considered which means temperatures that do not directly affect the damage of the component.

“…The most popular areas of application are the supervision of fatigue phenomena and cracks in steel structures [ 1 , 2 , 3 , 4 ], rolling elements in bearings [ 5 , 6 ] or the occurrence of partial discharges in power transformers [ 7 , 8 ] and medium voltage switchgears [ 9 , 10 , 11 ]. There have been attempts at recognizing AE signals in low voltage insulated gate bipolar transistors (IGBTs) [ 12 , 13 , 14 , 15 , 16 ] even with changes of junction and case temperature [ 17 ]. It must be noted that AE tests were applied to small packaging low-voltage semiconductors (without electrical insulation inserted between AE sensor and device case) but it can be assumed that the propagation of elastic waves in much bigger structures will behave differently because of the extended internal volume of different types of packaging and the use of insulating inserts for medium-voltage operation.…”

Modern seagoing ships are often equipped with converters which utilize semiconductor power electronics devices like thyristors or power transistors. Most of them are used in driving applications such as powerful main propulsion plants, auxiliary podded drives and thrusters. When it comes to main propulsion drives the power gets seriously high, thus the need for use of medium voltage power electronics devices arises. As it turns out, power electronic parts are the most susceptible to faults or failures in the whole electric drive system. These devices require efficient cooling, so manufacturers design housings in a way that best dissipates heat from the inside of the chips to the metal housing. This results in susceptibility to damage due to the heterogeneity of combined materials and the difference in temperature expansion of elements inside the power device. Currently used methods of prediction of damage and wear of semiconductor elements are limited to measurements of electrical quantities generated by devices during operation and not quite effective in case of early-stage damage to semiconductor layers. The article presents an introduction and preliminary tests of a method utilizing an acoustic emission sensor which can be used in detecting early stage damages of the gate turn-off thyristor. Theoretical considerations and chosen experimental results of initial measurements of acoustic emission signals of the medium voltage gate turn-off thyristor are presented.
