Modular multilevel converter (MMC) is a promising multilevel topology for high-voltage applications that has been developed in recent years. The control of MMCs has been analyzed in detail in many papers, showing that the converter capacitors can be kept charged and balanced by controlling the circulating current of each leg. The set-point signal of the circulating current is probably the most difficult...
Passive three-phase rectifier circuits are very popular for ac-dc power conversion. However, they do not have the capability to reverse the power flow, which is demanded by some recent potential smart-grid applications, such as vehicle-to-grid (V2G) power transfer. As an alternative, this paper analyzes the behavior of three-phase ac-dc matrix converters. Among the modulation strategies that minimize...
The main topic of this paper is the combination of two different technologies, i.e. the technology of tubular permanent magnet (PM) actuators, and the technology of multiphase drives. An electric drive consisting of two five-phase PM tubular actuators fed by a single five-phase inverter is described. The control scheme of the drive for position control is presented and the performance of the drive...
