The fuzzy C-means clustering algorithm(PCM) to the fuzzy kernel C-means clustering algorithm (FKCM) to effectively perform cluster analysis on the diversiform structures are extended, such as non-hyperspherical data, data with noise, data with mixture of heterogeneous cluster prototypes, asymmetric ...

In view of the DC fault current isolation deficiency for the conventional half-bridge sub-module (HBSM) based modular multilevel converter (MMC), this paper presents an improved MMC topology. Both quasi reverse blocking submodules (QRBSMs) and current limit modules (CLMs) are employed to improve the...

Solid-state transformers (SSTs) could serve as interfaces between a medium-voltage (MV) AC grid and a low-voltage (LV) DC load or source, i. e., could be employed in applications with power supply character such as traction auxiliary supplies or rack-level power supplies in future datacenters. For h...

The Little Box Challenge (LBC) was a competition sponsored by Google and the IEEE Power Electronics Society in 2014-2015, where participants were challenged to design a high power-density single-phase 2 kVA inverter. This paper surveys the designs from eight different participating teams, inc...

A relative position and attitude coupled sliding mode controller is proposed by combining the standard super twisting (ST) control and basic linear algorithm for autonomous rendezvous and docking. It is schemed for on-orbit servicing to a tumbling noncooperative target spacecraft subjected to extern...
