This paper presents an evaluation of the performance improvements of using hybrid IGBT modules; Silicon (Si) IGBT and Silicon Carbide (SiC) Diode, in an 225kW dc-dc converter for an electrical storage based light rail vehicle (tramway). First an experimental characterization of the conventional and hybrid IGBT modules is carried out. Second, based in this characterization, the power loss reduction...
A series of reliable and cost-effective microbioassay-based techniques for routine water quality monitoring were developed and tested on a recently developed irrigation area in western Spain. Results from these assays were compared to a screening-level risk characterisation based on pesticide concentrations in water samples from the study area. The levels of 147 pesticides were measured in irrigation...
In Medium Voltage grid-connected high power converters, due to switching frequency limitations, bulky and expensive passive filters are needed in order to limit the harmonic content in the point of common coupling (PCC). In this paper, a design procedure that optimizes the cost and volume of a LCL filter is proposed and experimentally validated, taking into account the effect of current and voltage...
