Abstract
This paper proposes a masterless control strategy for parallel active front-end (AFE) systems for off-board electric vehicle (EV) charging and stationary applications.
The proposed solution enables high modularity in AC-DC power converters designated for EV charger systems, where the AFE modules can be separated and
recombined, enabling them to be more versatile, flexible and scalable. The presented AFE rectifier system consists of several self-sufficient modules with distributed control that can exchange data through CAN bus. The proposed system
has functions like dynamic resource allocation, automatic interleaving, circulating current control, accurate current sharing and demonstrates increased fault tolerance. In this paper, the main operating principle of the masterless
control of modular AFE rectifier systems is explained. Moreover, the performance of the AFE rectifier system supplying power to a 100kW off-board DC charger is
demonstrated by MATLAB Simulink with changing load, module failures and possible manufacturing flaws.
