Project Details


Renewable and sustainable energy has recent years been driving the electrification processes in the energy sector with expansion of e.g. power-2-X, wind-, photovoltaic- and traction applications being some of the major political agendas towards 2030. This transition towards renewable and sustainable energy is driving the demand for increased efficiency and power handling capability of power electronic converter systems. This demand has driven the emergence of the disruptive wide bandgap power electronics technology. However, the wide bandgap devices brings many challenges from a power electronic converter design perspective, with one of the main contributors being the fast switching speeds. In prevalent Si-based power electronics converter systems, minimizing parasitic inductance has been of main concern due to high di/dt and slow switching speed (dv/dt). However, with the fast switching speeds of the wide bandgap devices and the potential to increase operating voltage levels the design regime of modern power converters is shifting towards minimizing parasitic capacitive couplings due to high dv/dt causing high-frequency, high amplitude capacitive displacement currents in the power electronics converter systems. In the literature these effects of the capacitive displacement currents are often characterized and addressed as electromagnetic interference in the power electronics converter systems, however different other measures such as system reliability and efficiency decrease due to these capacitive displacement currents should likewise be covered by the literature. To overcome these challenges, the designers of wide bandgap enabled power electronics converters should consider both inductive and capacitive parasitic circuit elements during the design phase of the product and understand the effects of these parasitic circuit elements to obtain optimized design using wide bandgap power semiconductor components. In this project the combined physics based and behavioural based analytical models will be linked and the contributions from individual sub-components will be used to evaluate the effects of the intra-component parasitic inductive and capacitive couplings on the overall system level performance, achieving design guidelines with high applicability for system level designers.
