Two-stage single-phase rectifiers, which comprises a front-end ac-dc converter and a downstream DC-DC stage, are widely used in electric vehicle onboard charger applications. In this context, the implementation of bidirectional power transfer capabilities has gained considerable attention. Then, Totempole power factor correction and Dual Active Bridge converters emerge as commendable choices for enhancing the efficiency of this configuration.

The aim of this thesis is investigate and design a small antenna which can be embedded onto a Polyethylene substrate (used for making roof tiles). The antenna can be used to harvest ambient energy by connecting it to a rectifier. Due to the dimensional constraints of a roof tile as well as the materials used, there are limitations imposed on the antenna size, and thus the radiation efficiency and bandwidth often become a limiting factor in the overall performance of the system.

The development of a small signal model that accurately reflects dynamic processes plays an essential role in the stability analysis and control of power systems. The main components in a microgrid power system are synchronous generators, the electrical network, electrical loads, and inverters. A method to derive the microgrid state-space model is proposed in the article.

The modernization of the world has considerably reduced the prime sources of energy such as coal, diesel and gas. Thus, alternative energy sources based on renewable energy have been the main concentration nowadays to address the world’s energy demand as well as restrict global warming. Solar energy is the main source used to generate electricity through photovoltaic (PV) system. However, the output of PV power is normally intermittent.

In this paper, we present simulation and evaluation of sensitivity of electrical and mechanical effects of MEMS based capacitive pressure sensor with rectangle diaphragm using COMSOL Multiphysics. This includes diaphragm deflection, sensitivity and linearity analysis, capacitance and thermal considerations. Capacitance values are plotted under uniform external pressure 10kPa. Selected materials include silicon and carbon, acknowledging that carbon has shown the best and steady result. Simulation results also show how the capacitance and diaphragm deformation varies under increasing pressure.

Leachate is a noticeable pollution problem because it contains a considerable amount of persistent organic pollutants (POPs). If leachate isn't treated thoroughly, its leak will negatively affect the environment. Therefore, appropriate treatment technologies are required to remove them. Bio-Electro-Fenton (BEF) is a new method using microorganisms such as electrolytes to convert chemical energy into electricity to help create H2O2 support advanced oxidation process (AOPs).
