In this study, a set of multiple maximum power point trackers to track maximum power output and to increase power generation efficiency of solar panels were designed and implemented, and they are combined with a bi-directional inverter to form a DC microgrid distribution system. The multiple maximum power point trackers can be operated independently or in parallel, and can be operated in either boost or buck mode according to input voltage level. In addition, the trackers allow on-line plug and unplug, increasing application feasibility. The system uses a microprocessor of TMS320LF2406A to fulfill protection functions and perturb and observe algorithm to achieve maximum power point tracking. Finally, by combining the bi-directional inverter and the maximum power point trackers, and under load change and input power variation, hardware measurements were conducted. Measured results have shown that power conversion efficiency of the maximum power point trackers can reach 99%, and the overall system when combining the bi-directional inverter can achieve the highest efficiency of 96%.
