Carbon blacks, which consist of the assemblies of small graphene clusters having a spherical concentric packing structure, are amorphous and have widely been used as catalyst supports for proton exchange membrane fuel cell (PEMFC) electrodes. However, poor electrochemical corrosion resistance during extended use and repeated cyclic operation of PEMFCs shortens their practical device lifetime; surface...
For 3-phase applications, an isolated multilevel inverter employing 3-phase transformers can reduce the number of transformers compared with that of using single- phase transformers. However it needs a large number of switches. To solve this problem, we propose a modified 3-phase isolated multilevel inverter adopting common-arm scheme. Phase angle control based on equal-area method is presented to...
