Abstract: According to an aspect, there is provided an apparatus for performing the following. The apparatus maintains, in a memory, information on a computational model for thermal behavior of layers of an insulated-gate bipolar transistor, IGBT, module (501). The apparatus obtains measurements of the dissipated power at the semiconductors and the ambient temperature and determines one or more current values of one or more temperatures of the IGBT module (501) based on a switching delay of the IGBT module (501). The apparatus calculates a current estimate of a joint state-parameter space of the computational model using a Bayesian filter and the computational model taking as inputs the dissipated power and the ambient temperature. The joint state-parameter space comprises the one or more temperatures, one or more thermal loss parameters and one or more wear parameters. The one or more current values of the one or more temperatures are used as observations in the Bayesian filter.

Abstract: A full-bridge inverter (100) based on a unipolar switching scheme comprises a first branch (102) and a second branch (104) in parallel between a first DC node (10) and a second DC node (12), the first branch (102) comprising a first higher switch (106) and a first lower switch (108) in series, and the second branch (104) comprising a second higher switch (110) and a second lower switch (112) in series. A filter circuit (150) comprises a first inductor (152) and a second inductor (158). One pin (154) of the first inductor (152) is coupled with a first branch conductor (120), and the first branch conductor (120) is coupled between the first higher switch (106) and the first lower switch (108), and an opposite pin (156) of the first inductor (152) is electrically coupled with a first output node (190). One pin (160) of the second inductor (158) is coupled with a second branch conductor (122), the second branch conductor (122) is coupled between the second higher switch (110) and the second lower switch (112), and an opposite pin (162) of the second inductor (158) is coupled with a second output node (192) of the full-bridge inverter (100). A first filtering unit switch (164), a first filter diode (166), a second filter diode (168) and a second filtering unit switch (170) in series are coupled between the first branch conductor (120) and the second branch conductor (122), cathodes of the first diode (166) and the second diode (168) are coupled together. A cathode of a third filter diode (172) is coupled with the first output node (190), and a cathode of a fourth filter diode (174) is coupled with the second output node (192). The anodes of the third diode (172) and the fourth diode (174) are coupled together. A third inductor (176) is coupled between the cathodes of the first diode (166) and the second diode (168) and the anodes of the third diode (172) and the fourth diode (174).

Abstract: A ballast water treatment apparatus (100) and a ballast water treatment system (1) having a ballast water treatment apparatus (100) are provided. The ballast water treatment apparatus (100) includes a ballast water transport line (10) configured to transport ballast water between a first location (A) and a second location (B), the transported ballast water being passed through at least one injector (20), and a plasma generation device (30) configured to be fed with a feed gas comprising oxygen, and configured to generate a feed gas plasma (35) by a non-thermal discharge in a discharge area (36) to provide a treated gas at a treated-gas outlet (37). The injector (20) comprises a liquid passage (21) having an area (22) constructed such as to increase a velocity of the passed-through water in a region (26) of increased velocity, and an injector gas inlet (25) provided in the region (26) of increased velocity. The treated-gas outlet (37) is in gaseous connection with the injector gas inlet (25).
