摘要： A power generation system including a photovoltaic (PV) module to generate direct current (DC) power is provided. The system includes a controller to determine a maximum power point for the power generation system and a boost converter for receiving control signals from the controller to boost the power from the PV module to a threshold voltage required to inject sinusoidal currents into the grid.

摘要： An optically powered MEMS gate driver includes a photovoltaic converter configured to receive a light signal from a light source and output a DC supply voltage for a MEMS gate driver in response thereto. The MEMS gate driver further includes a DC to DC converter electrically coupled to the photovoltaic converter and configured to output a line level DC voltage in response to the DC supply voltage. An electrical circuit, also included as a portion of the MEMS gate driver is electrically coupled to both the photovoltaic converter and the DC to DC converter is configured to receive the supply voltage and the line level voltage and to output a line level drive signal in response thereto. The optically powered MEMS gate driver is self-contained within a common EMI enclosure thus providing isolation between the gate driver and command signal electronics.

摘要： A power inverter system includes a plurality of power inverters such as solar inverters receiving power from at least one energy source. Each power inverter includes algorithmic maximum peak power tracking (MPPT) software or integrated MPPT firmware to calculate its own potential real power. A controller is in electrical communication with selected power inverters that are operating in curtailed modes of operation and commands each selected power inverter to shift its power production duties and to perform MPPT sweeps. Each selected power inverter then calculates its own potential real power capability in response to corresponding MPPT sweep data. The potential real power capability information is received by the controller that transmits the information to a power utility allowing the power utility to more efficiently utilize real and reactive power available by the plurality of power inverters
