PHOTOVOLTAIC ENERGY EXTRACTION WITH MULTILEVEL OUTPUT DC-DC SWITCHED CAPACITOR CONVERTERS |
摘要 |
Switched capacitor multilevel output DC-DC converters can be used as panel integrated modules in a solar maximum power point tracking system. The system can also include a central input current-controlled ripple port inverter. The system can implement per panel MPPT without inter-panel communication, electrolytic capacitors or per panel magnetics. A Marx converter implementation of the switched capacitor module is studied. Average total efficiencies (tracking×conversion) greater than 93% can be achieved for a simulated 510 W, 3 panel, DC-DC system.
