Abstract

This paper presents a redundant operation of a modular three-phase AC/DC converter based on a distributed control method. For the flexibility and redundant operation purpose, each converter module employs an individual controller to control the power converter operation. The mathematical model to design the output voltage control is described in this paper. The performance evaluation was conducted via a four-module of a single phase CUK AC/DC converter, with a -48V DC output voltage and a 750W load. The proposed system is verified by simulations using MATLAB/Simulink. The system has achieved as the following: a tight output voltage regulation, a current sharing of each module is quite good, and a redundant operation of the system can be operated through the distributed control.
