Problem: Electrolytic capacitors and per panel magnetics have limited lifetime and are expensive. Technology: This invention proposes per-panel Maximum Power Point Tracking (MPPT) for widespread solar arrays. A full system approach is presented utilizing switched capacitor multi-level DC-DC and a central ripple-port inverter to replace the multiple inductors used in current PV technology.
Benefits:
1) Substantial cost reduction and prolonged lifetime 2) Average total efficiencies of tracking and conversion greater than 93% for a 510 W 3 panel DC-DC system
