Abstract


This paper presents a decentralized control algorithm for interleaved converters for high reliability
application. In previous literature, a master control provides information on the system configuration in order to generate the different carriers. The whole premise of the proposed algorithm is that each module only communicates with its two immediate neighbors which reduce communication latency. Using only the neighbors proper interleaving of the carriers and balancing the converter leg currents is achieved. Carriers from each converter automatically adjust their phase, as modules are added or removed dynamically. Such implementation offers a completely
decentralized control which makes it fully modular. Results of the controller are presented using a real-time simulator.
