    摘要: A system and method for converting DC from one or more sources to AC power utilizing a novel partitioning scheme are disclosed. This partitioning scheme is particularly well suited for photovoltaic (PV) microinverter applications. The primary goals are to make installation, operation and maintenance of the system safe and simple. Secondary goals are to improve reliability and lifetime of the converter in a cost effective manner. In one embodiment, the microinverters are placed in one-to-one proximity with the photovoltaic modules, each proximate microinverter incorporating a reduced number of functions and components. Remaining common functions and controls are implemented separately.

    摘要: A replaceable photovoltaic inverter is mounted on each of a plurality of photovoltaic module for the conversion of direct current, produced by the photovoltaic cells, to alternating current. The inverter is coupled to a mounting bracket on the photovoltaic module such that is can be easily replaced. Replacement of an individual photovoltaic module inverter can occur during continuous operation of the photovoltaic module system with minimal impact on overall power production. The inverter is also mounted apart from the photovoltaic module to facilitate heat transfer generated by operation of the inverter.

    摘要: A photovoltaic module-mounted AC inverter circuit uses one or more integrated circuits, several power transistors configured as switches, several solid-dielectric capacitors for filtering and energy storage, several inductors for power conversion and ancillary components to support the above elements in operation. The integrated circuit includes all monitoring, control and communications circuitry needed to operate the inverter. The integrated circuit controls the activity of pulse-width modulated power handling transistors in both an input boost converter and a single-phase or multi-phase output buck converter. The integrated circuit also monitors all power processing voltages and currents of the inverter and can take appropriate action to limit power dissipation in the inverter, maximize the available power from the associated PV module and shut down the inverter output if the grid conditions so warrant. The integrated circuit implements power line communications by monitoring the AC wiring for signals and generating communications signals via the same pulse-width modulation system used to generate the AC power. Communications is used to report inverter and PV module status information, local identification code and to allow for remote control of inverter operation.
