The Modular Multilevel Converter for High Step-Up Ratio DC-DC Conversion
High step-up ratio DC-DC converters with megawatt ratings are of interest in wind turbine interfaces and high-voltage direct-current systems. The modular multilevel DC-DC converter based on the standard boost converter topology but with the normal single switches replaced by a number of capacitor-clamped sub-modules. The converter is operated in resonant mode with resonance between sub-module c...
متن کاملModified Modular Multilevel Converter
The modular multilevel converter (MMC) is receiving extensive research interests in high/medium voltage applications due to its modularity, scalability, reliability, high voltage capability and excellent harmonic performance. The submodule capacitors are usually quite bulky since they have to withstand fundamental frequency voltage fluctuations. To reduce the capacitance of these capacitors, th...
متن کاملAn Efficient High-Step-Up Soft-Switching Boost Converter for Photovoltaic Application
In this paper an efficient high step-up converter with a coupled- inductor with soft- switching operation is presented. The proposed topology includes a coupled-inductor boost converter for raising the voltage gain. Moreover, a simple auxiliary resonant circuit composed of an auxiliary switch, a clamping diode and a resonant tank (inductor, capacitor), is adopted in this paper. The coupled-indu...
