A distributed optimal control scheme for interleaved dc-dc converters

This paper extends the recently introduced approach in optimal control methods for fixed frequency switch-mode dc-dc converters to the parallel interleaved synchronous step-down circuit topology with N branches. Due to the prohibitive complexity of modelling and controlling such potentially large systems a distributed model predictive control scheme is employed allowing for the related optimal control problem to be efficiently formulated and solved off-line for each local controller. Simulation results are provided to illustrate the outcome of the proposed approach.
