In the application of rail transit vehicles, when using typical wireless power transfer (WPT) systems with series–series (SS) compensation supply power for supercapacitors, the output current is in an approximately inverse relationship with the duty cycle in a wide range. This renders the typical buck circuit control inappropriate. In order to help resolve the above issues, this paper designs i...

For developing a large-scale combined system with a number of distributed resources, an appropriate compensation strategy based on the system components and changeable condition must be configured to handle the characteristics of the internal systems. Since renewable sources generate various fluctuations, the compensation plans for the storage device connected along with the sources should be s...

This work presents a reactive control strategy for loading and sudden unloading of an elbow effort-compensation device controlled in force. Through this strategy, addition to individual's forearm weight, external load can be detected adaptively compensated via feed-forward force reference, facilitating the execution arbitrary movements by wearer. In case contact/load loss, power-aware is implem...

This paper proposes a photovoltaic (PV) and battery interfaced series hybrid active power filter (SHAPF), which consists of series active power filter and an LC shunt passive filter. The main benefits of the proposed system provide the compensation against the voltage harmonics, current harmonics and voltage interruption for the whole day. A series active power filter (SAPF) demands a source of...

Renewable energy resources (RES) are being increasingly connected in distribution systems by utilizing power electronic converters. However, the extensive use of power electronics has resulted in a rise in power quality (PQ) concerns faced by the utility. A novel control strategy implementing reference compensation current was proposed in this paper. So that these grid-connected inverters can a...
