  2. Maximum power point tracking - Wikipedia

    en.wikipedia.org/wiki/Maximum_power_point_tracking

    Power/Voltage-curve of a partially shaded PV system, with marked local and global MPP. Maximum power point tracking (MPPT), [1] [2] or sometimes just power point tracking (PPT), [3] [4] is a technique used with variable power sources to maximize energy extraction as conditions vary. [5]

  3. Spacecraft bus (James Webb Space Telescope) - Wikipedia

    en.wikipedia.org/wiki/Spacecraft_Bus_(James_Webb...

    Communications with the central computer is via a 1553 bus. In addition to the power switches, processors for the SAR MPPT algorithm are located in the PCU, along with some telemetry processors, processors to detect when the spacecraft has disconnected from the launch upper stage, and some cryo-cooler controllers.

  4. Power management integrated circuit - Wikipedia

    en.wikipedia.org/wiki/Power_management...

    A PMIC may include battery management, voltage regulation, and charging functions.It may include a DC to DC converter to allow dynamic voltage scaling.Some models are known to feature up to 95% power conversion efficiency.

  5. Photovoltaics - Wikipedia

    en.wikipedia.org/wiki/Photovoltaics

    These modules perform maximum power point tracking (MPPT) for each module individually, measure performance data for monitoring, and provide additional safety features. Such modules can also compensate for shading effects, wherein a shadow falling across a section of a module causes the electrical output of one or more strings of cells in the ...

  6. Pulse-width modulation - Wikipedia

    en.wikipedia.org/wiki/Pulse-width_modulation

    The longer the switch is on, the higher the total power supplied to the load. Along with maximum power point tracking (MPPT), it is one of the primary methods of controlling the output of solar panels to that which can be utilized by a battery. [2]

  7. Solar inverter - Wikipedia

    en.wikipedia.org/wiki/Solar_inverter

    Internal view of a solar inverter. Note the many large capacitors (blue cylinders), used to buffer the double line frequency ripple arising due to single-phase ac system.. A solar inverter or photovoltaic (PV) inverter is a type of power inverter which converts the variable direct current (DC) output of a photovoltaic solar panel into a utility frequency alternating current (AC) that can be ...

  8. Grid-tie inverter - Wikipedia

    en.wikipedia.org/wiki/Grid-tie_inverter

    Inverter for grid-tied solar panel Three-phase grid-tie inverter for large solar panel systems. A grid-tie inverter converts direct current (DC) into an alternating current (AC) suitable for injecting into an electrical power grid, at the same voltage and frequency of that power grid.
