In a non-ideal scenario for an IPT system, a transmitter coil magnetically couples with both the receiver coil and the adjacent transmitter coils. Such mutual coupling between transmitter coils is not desirable since they affect the maximum power that the transmitter can transfer to the receiver. A dual frequency IPT (DFIPT) system focuses on...

The global demand for natural gas is growing as gas is a cleaner partner to renewable energy than oil and coal. To be able to exploit remote offshore gas fields Shell is developing a floating facility to produce, treat and liquefy natural gas, called a Floating Liquid Natural Gas (FLNG) vessel. To make the FLNG vessel a cost effective option for...

In a monolithic perovskite/c-Si tandem device, the perovskite top cell has to be deposited onto a flat c-Si bottom cell without anti-reflective front side texture, to avoid fabrication issues. We use optical simulations to analyze the reflection losses that this induces. We then systematically minimize these losses by introducing surface...

This thesis focuses on the search for the optimal converter which can be used as a single solution for both EV charging and PV energy production. The three port converter must be able to charge the battery from both the grid and solar power, and inject current to the grid from both the solar array and the EV battery, allowing V2X operation....

Electrical vehicles (EVs) can be charged wirelessly with an inductive power transfer (IPT) system that uses a magnetic field to deliver power to the EV. Such a system could be embedded in the highway to charge EVs while they are driving. The magnetic field of the IPT system is created using coils that are exited with a high frequency current....

The inertial response plays a vital role in electrical networks to reduce the rate of change of frequency (RoCoF) following a contingency event. If the inertia has a low or zero value due to a lack of synchronous generators, then the electrical network might experience large undesirable frequency deviations. To overcome this problem, in previous...

Due to the emergence of renewable sources of energy and the progress in sustainable technologies, it could become very interesting in terms of energy savings and cost efficiency to switch the consumer level of the electrical network from AC to DC. This way, less power conversion would be required, and the meshing of the grid would be possible,...
