Multi-objective Design and Benchmark of Wide Voltage Range Phase-Shift Full Bridge DC/DC Converters for EV Charging Application

This article presents an analysis, multiobjective design, and benchmark of three modified 3 phase shift full-bridge (PSFB) converters that are well-suited for electric vehicle (EV) battery charging applications, covering both typical battery voltage classes (400 and 800 V). These three modified PSFB converters, denoted as the t-PSFB, r-PSFB,...

PV to USB-C adapter for Rural Electrification

DC/DC converter for EV charging from trolley grid

Trolley bus systems provide modern low-emission public transport for urban areas. The trolley bus demands a peak power at acceleration that is at least 4 times the regular operational power demand of the bus. To provide the acceleration power for a fleet of buses, the substations are inherently oversized. With the excess capacity in the trolley...

Modeling, simulation and control of the alternate arm converter

In this study a new hybrid voltage source converter based topology is modeled, simulated and controlled. This new topology is usually known as alternate arm converter. For the simulation developing MATLAB/Simulink software is used. With the MATLAB/Simulink software the model of alternate arm converter is developed from the scratch. Firstly the...

DC/DC Converters for Multiterminal HVDC Systems: Based on Modular Multilevel Converter

The increase in the energy demand has resulted in searching for new energy sources. Due to the increased prices of fossil fuels and the environmental issues, renewable energy sources has become popular in Europe. Renewable energy generation such as wind, solar and wave has point-to-point connections with the main grid. In order to minimize the...

Modeling of parasitic elements in high voltage multiplier modules

It is an inevitable trend that the power conversion module will have higher switching frequency and smaller volume in the future. Bandgap devices, such as SiC and GaN devices, accelerate the process. With this process, the parasitic elements in the module will probably have stronger influence on circuit operations than before. In this thesis,...

Analysis and Design of MHz-range Wireless Power Transfer Systems for Implantable Devices

Wearable and implantable devices are becoming more and more common as time goes by and one of the major bottlenecks in their development is the power delivery. In order to tackle this problem, energy harvesting arises an option to bring these devices one step closer to complete autonomy. Among the available mechanisms for harvesting, near-field...
