A Flexible Maximum Power Point Tracking Control Strategy Considering Both Conversion Efficiency and Power Fluctuation for Large-inertia Wind Turbines

Energies, 2017
In wind turbine control, maximum power point tracking (MPPT) control is the main control mode for partial-load regimes. Efficiency potentiation of energy conversion and power smoothing are both two important control objectives in partial-load regime ...

Frequency conversion to augment power conversion efficiency in photovoltaic devices

2024 24th International Conference on Transparent Optical Networks (ICTON)
To attain high power conversion efficiencies in photovoltaic devices majorly requires proper matching between the optoelectronic properties of the photoactive layer and the solar emission spectrum for maximum absorption of the solar photon flux. Up- and down-conversion using rare earth-doped layers represent the predominantly used approaches to tune ...
