Abstract
A microinverter for use with a single photovoltaic (PV) panel. The self-contained unitary package includes a low voltage power module (LVPM), a high voltage power module (HVPM), a transformer passing power between the two modules, a DC filter to filter incoming DC power from the PV panel, and an AC power to filter 3-phase power to be provided to an AC power bus connected to an AC power grid. The microinverter package couples to a single PV panel and converts incoming DC power from the PV panel to 3 phase AC power suitable for the AC power grid. All necessary electronics and conversion circuitry and components are contained in the package and provides a plug and play solution between the PV panel and the AC grid.
