CURRENT BALANCING IN MULTIPHASE CONVERTER BASED ON INTERLEAVING TECHNIQ UE USING FUZZY LOGIC

In the field of power electronics, multiphase converter is used to achieve fast dynamic response, smaller filters and better packaging. Typically, multiphase buck converter have several paralleled power stages with current loops to increase dynamic response using current mode control and to avoid current unbalanc e among phases. The proposed multiphase converter based on interleaving technique results in cancellation of the current ripple generated at the output of each converter cell. The interleaving technique provides an intrinsic self - balance mechanism which is used to avoid the current unbalance. In addition fuzzy logic has been implemented on multiphase buck converter to achieve dynamic voltage regulation and better current balance .
