Hu, Yihua and Zeng, Rong and Cao, Wenping and Zhang, Jiangfeng and Finney, Stephen J. (2015) Design of a modular, high step-up ratio DC–DC converter for HVDC applications integrating offshore wind power. IEEE Transactions

High power and high voltage gain DC-DC converters are key to high-voltage DC (HVDC) power transmission for offshore wind power. This paper presents an isolated ultra-high step-up DC-DC converter in matrix transformer configuration. A flyback-forward converter is adopted as the power cell and the secondary side matrix connection is introduced to increase the power level and to improve fault tole...

Three Dimensional Transient Numerical Modeling of Temperature Distribution and Output Power in Photovoltaic Module

According to the effect of temperature on the output power of a photovoltaic module, this research tries to calculate the temperature distribution in a photovoltaic module by numerical solving of the energy balance equations. Therefore, its output power can be accurately predicted. For this purpose, several photovoltaic modules are modeled in detail in the COMSOL software. A new method for calc...

New multi-stage DCeDC converters for grid-connected photovoltaic systems

Renewable energy is high on international and national agendas. Currently, grid-connected photovoltaic (PV) systems are a popular technology to convert solar energy into electricity. Existing PV panels have a relatively low and varying output voltage so that the converter installed between the PVs and the grid should be equipped with high step-up and versatile control capabilities. In addition,...
