A transformerless microinverter is described that is intended for integration into building materials such as residential roof shingles. The inverter achieves low profile (3 mm), high efficiency (95.1%) and high reliability capacitive energy storage using 125degC ceramics. It is intended to interface a 25 W photovoltaic array such as a small thin-film residential roof shingle to the 120 V AC utility...
Energy storage requirements for converters with a dc port and a single-phase grid-connected port are evaluated, based on the unavoidable double-frequency power requirement. The minimum energy storage requirement is linked to a minimum capacitance requirement for converters that use capacitance energy storage. It is shown how to employ a ripple power port to manage energy storage and decouple capacitor...
