Switched capacitor, module integrated converters, photovoltaic, ripple port inverter
Widespread grid generation of PV
Electrolytic capacitors and per panel magnetics have limited lifetime and are expensive.
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.
