  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 ...

    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. 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.

  5. 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 ...

    Principles of Electronics presents a broad spectrum of topics, such as atomic structure, Kirchhoff's laws, energy, power, introductory circuit analysis techniques, Thevenin's theorem, the maximum power transfer theorem, electric circuit analysis, magnetism, resonance, control relays, relay logic, semiconductor diodes, electron current flow, and ...

  7. Input impedance - Wikipedia

    en.wikipedia.org/wiki/Input_impedance

    The source network is the portion of the network that transmits power, and the load network is the portion of the network that consumes power. For an electrical property measurement instrument like an oscilloscope , the instrument is a load circuit to an electrical circuit (source circuit) to be measured, so the input impedance is the impedance ...

    The red curve shows the power in the load, normalized relative to its maximum possible (which occurs when R L == R S).The black curve shows the power transfer efficiency η, which asymptotically approaches the maximum of 100% as the ratio / increases.
