摘要: Switched capacitor multilevel output DC-DC converters are evaluated as panel integrated modules in a solar maximum power point tracking system. The recommended system includes central input current-controlled ripple port inverter. Potential benefits include per MPPT without inter-panel communication, electrolytic capacitors or magnetics. Statistical methods used to predict average and conversion efficiencies. A particular implementation of the switched module is studied — Marx converter. Average total efficiencies (tracking × conversion) greater than 93% predicted for simulated 510 W, 3 panel,
