Development of control strategy of DC-DC converter for optimal operation of PV powered Electrolyser

With the current need of implementing renewable energy sources to combat climate change, significant developments are being done into storage options for these intermittent energy sources. Green Hydrogen can be produced by the connection of a renewable energy source to an electrolyser which produces hydrogen, in this project the Photovoltaic (PV...

Auto-Resonant Detection Method for Optimized ZVS Operation in IPT Systems With Wide Variation of Magnetic Coupling and Load

In wireless charging systems, the H-bridge converter's switching frequency is set close to the system's natural resonance for achieving optimized zero voltage switching (ZVS). Variations to the system's natural resonance are commonly tracked by following the changes in the resonant current's polarity, i.e., current zero-crossings. The main...

System design and control of a novel ocean wave energy converter array

There is a great amount of wave power in earth's oceans. The amount of power harvested for electricity is however very small in comparison to solar and wind. One of the reasons for this is the lack of consensus on the best design of wave energy converters. This thesis develops a novel system design for a wave energy converter array that has...
