A Modular DC-DC Converter Topology Based On A Three-Level DC-DC Converter For Distributed Fuel Cell Architecture
IEEE Energy Conversion Congress and Exposition(2019)
摘要
This paper presents a new modular DC-DC converter topology. As modular topology, the converter can be used for several energy sources. Each converter module is based on a three-level DC-DC converter, which contains two output capacitors. The first module shares the second capacitor in common with the first capacitor of the next module. In this way, N-module can be utilized for N-energy source. The output capacitor voltages are balanced thanks to the proposed topology and the controller. The controller is based on the indirect-sliding mode controller where the input current of each energy source and the output voltage balancing are taken into account. Simulation and experimental results are provided to validate the topology.
