    Abstract: 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. 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 based on a switching delay of the IGBT module. 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 includes 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 based on a unipolar switching scheme includes a first branch and a second branch in parallel between a first DC node and a second node, the first branch including a first higher switch and a first lower switch in series, and the second branch including a second higher switch and a second lower switch in series. A filter circuit includes a first inductor and a second inductor. One pin of the first inductor is coupled with a first branch conductor, and the first branch conductor is coupled between the first higher switch and the first lower switch, and an opposite pin of the first inductor is electrically coupled with a first output node. One pin of the second inductor is coupled with a second branch conductor, the second branch conductor is coupled between the second higher switch and the second lower switch, and an opposite pin of the second inductor is coupled with a second output node of the full-bridge inverter. A first filtering unit switch, a first filter diode, a second filter diode and a second filtering unit switch in series are coupled between the first branch conductor and the second branch conductor, cathodes of the first diode and the second diode are coupled together. A cathode of a third filter diode is coupled with the first output node, and a cathode of a fourth filter diode is coupled with the second output node. The anodes of the third diode and the fourth diode are coupled together. A third inductor is coupled between the cathodes of the first diode and the second diode and the anodes of the third diode and the fourth diode.

    Abstract: A ballast water treatment apparatus and a ballast water treatment system having a ballast water treatment apparatus are provided. The ballast water treatment apparatus includes a ballast water transport line configured to transport ballast water between a first location and a second location, the transported ballast water being passed through at least one injector, and a plasma generation device configured to be fed with a feed gas optionally comprising oxygen, and configured to generate a feed gas plasma by a streamer type discharge in a discharge area to provide a treated gas at a treated-gas outlet. The injector includes a liquid passage having an area constructed such as to increase a velocity of the passed-through water in a region of increased velocity, and an injector gas inlet provided in the region of increased velocity. The treated-gas outlet is in gaseous connection with the injector gas inlet.
