  2. Maximum power transfer theorem - Wikipedia

    en.wikipedia.org/wiki/Maximum_power_transfer_theorem

    The theorem results in maximum power transfer from the power source to the load, but not maximum efficiency of useful power out of total power consumed. If the load resistance is made larger than the source resistance, then efficiency increases (since a higher percentage of the source power is transferred to the load), but the magnitude of the ...

  3. Impedance matching - Wikipedia

    en.wikipedia.org/wiki/Impedance_matching

    For example, a maximum power point tracker is used to extract the maximum power from a solar panel and efficiently transfer it to batteries, the power grid or other loads. The maximum power theorem applies to its "upstream" connection to the solar panel, so it emulates a load resistance equal to the solar panel source resistance. However, the ...

  4. Wireless power transfer - Wikipedia

    en.wikipedia.org/wiki/Wireless_power_transfer

    A drawback of resonant coupling theory is that at close ranges when the two resonant circuits are tightly coupled, the resonant frequency of the system is no longer constant but "splits" into two resonant peaks, [85] [86] [87] so the maximum power transfer no longer occurs at the original resonant frequency and the oscillator frequency must be ...

  5. Electrical efficiency - Wikipedia

    en.wikipedia.org/wiki/Electrical_efficiency

    As a result of the maximum power theorem, devices transfer maximum power to a load when running at 50% electrical efficiency. This occurs when the load resistance (of the device in question) is equal to the internal Thevenin equivalent resistance of the power source. This is valid only for non-reactive source and load impedances.

  6. Resonant inductive coupling - Wikipedia

    en.wikipedia.org/wiki/Resonant_inductive_coupling

    Wireless electric energy transfer for experimentally powering electric automobiles and buses is a higher power application (>10 kW) of resonant inductive energy transfer. High power levels are required for rapid recharging and high energy transfer efficiency is required both for operational economy and to avoid negative environmental impact of ...

  7. Maximum power point tracking - Wikipedia

    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]
