Abstract
A DSP-based improved maximum power point tracking (MPPT) approach for multiple solar array application is presented. It incorporates a "shared bus" current sharing method that can regulate many paralleled current mode DC/DC converters. The modular architecture eases the expansion of system power. The current sharing and MPPT performance of the proposed system is validated and evaluated by a 500-W prototype with two solar arrays.
