Abstract:
This article presents a method of current balancing for a multiphase converter using a single voltage sensor. This control approach uses the ripple measurement of the input voltage to determine the current unbalance. It uses local controllers associated with each switching-cell and allows current balancing to be performed in a distributed manner by implementing simple and identical computations in each one of them. The results obtained on a 3-phase 300V/60A converter demonstrate the robustness of the control. This approach can be generalized to any multiphase converter using a large number of phases.
