Simulation and Verification or Cu@Ag Core-shell Sintered Paste for Power Semiconductor Die-attach Applications

With the increasing application of wide bandgap materials such as silicon carbide and gallium nitride in power devices, the working temperature of power devices has been pushed further. Therefore, it brings higher requirements for packaging materials. Sintered silver is a widely accepted chip connection material. However, silver suffers from...

Reducing the need for communication in remote, natural waveform co-simulations of electrical power systems: An adaptive approach

Electrical power systems are becoming more interconnected and technologically diverse to accommodate ever increasing shares of non-dispatchable generation. These changes are imposing new requirements on the simulation of electrical power systems. One of these requirements is that simulations integrate models of different subsystems, developed by...

Comparison of Power-to-X-to-Power technologies for energy storage in 2030

The energy transition is advancing rapidly, and the Dutch electricity grid is changing with it. Increasing shares of variable renewable energy sources create mismatches between electricity supply and demand. These mismatches create a need for large-scale energy storage. Existing large-scale energy storage technologies are pumped hydro energy...

Speeding Up AC Circuit Co-Simulations Through Selective Simulator Decoupling of Predictable States

Co-simulation has become increasingly popular as a tool for dealing with the unprecedented complexity of modern engineering systems, such as electrical power systems and the AC circuits that compose them. Co-simulation is useful when migrating the models of each subsystem to a single monolithic simulator is either impractical or impossible,...

Simulations of steady and oscillating flow in diffusers

In this thesis diffuser performance will be simulated with computational fluid dynamics, which will be done with the program Ansys Fluent. The expanding geometry creates an adverse pressure gradient and under certain conditions there will also be separation.<br/><br/>At first a relative simple simulation will be done of a one-directional...

Storage sharing at import dry-bulk terminals: A case study at Gadani Energy Park

The Gadani Energy Park is a to-be build project in which ten coal-fired power plants are established at one location near the shore of Karachi, Pakistan. In the initial situation, all power plants manage their own on-shore operations. The objective of this study is to gain insight in the advantages and disadvantages of yard collaboration in bulk...

Low AC Loss in a 3 kA HTS Cable of the Dutch Project

are: a cable has to fit in an annulus of 160 mm, with two cooling stations at the cable ends only. Existing solutions for HTS cables would lead to excessively high coolant pressure drop in the cable, potentially affecting public acceptance of the project. A way out would be to substantially reduce AC losses from 1 down to about 0.1 W/m per phase...

Design of a Sustainable Electric Vehicle Charging Station

Electric vehicles only become useful in reducing greenhouse gas emissions, if the electricity used to charge their batteries comes from renewable energy sources. This thesis was conducted within the electric mobility framework of the Green Village, the project put forward to test the Green Campus Concept. The objective was to design a Station...

Automated Implant-Processor Design

As we move towards an aging population, it is likely that an increasing number of people will require an increasing diversity of implants, but at a lower cost to the society. Also, as computer technology progresses, smaller, more powerful, and less battery intensive implants can be designed. However, present implant design methodology is highly...
