  2. Power over Ethernet - Wikipedia

    en.wikipedia.org/wiki/Power_over_Ethernet

    In a passive PoE system, the injector does not communicate with the powered device to negotiate its voltage or wattage requirements but merely supplies power at all times. Common 100 Mbit/s passive applications use the pinout of 802.3af mode B (see § Pinouts ) – with DC positive on pins 4 and 5 and negative on 7 and 8, and data on 1 and 2 ...

  3. Current injection technique - Wikipedia

    en.wikipedia.org/wiki/Current_injection_technique

    To implement the current injection technique, current injection circuit was developed with results indicating that the injection of an additional current during its switching transient can reduce the reverse recovery charge of a given power diode and thyristor, and also reduce the tail current of insulated gate bipolar transistors.

  4. Bias tee - Wikipedia

    en.wikipedia.org/wiki/Bias_tee

    A bias tee is a three-port network used for setting the DC bias point of some electronic components without disturbing other components. The bias tee is a diplexer.The low-frequency port is used to set the bias; the high-frequency port passes the radio-frequency signals but blocks the biasing levels; the combined port connects to the device, which sees both the bias and RF.

  5. Integrated injection logic - Wikipedia

    en.wikipedia.org/wiki/Integrated_injection_logic

    Simplified schematic of an I2L inverter. Integrated injection logic (IIL, I 2 L, or I2L) is a class of digital circuits built with multiple collector bipolar junction transistors (BJT). [1] When introduced it had speed comparable to TTL yet was almost as low power as CMOS, making it ideal for use in VLSI (and larger) integrated circuits. The ...

  6. Phantom power - Wikipedia

    en.wikipedia.org/wiki/Phantom_Power

    A microphone or other device can obtain DC power from either signal line to ground terminal, and two capacitors block this DC from appearing at the output. R1 and R2 should be 6.81k ohms for "P48" 48-volt phantom. R3–6 and Zener diodes 1–4 deliberately clip the outputs to ±10v to protect a subsequent circuit from potentially large transients.

  8. Flyback converter - Wikipedia

    en.wikipedia.org/wiki/Flyback_converter

    Fig. 1: Schematic of a flyback converter. The flyback converter is used in both AC/DC, and DC/DC conversion with galvanic isolation between the input and any outputs. The flyback converter is a buck-boost converter with the inductor split to form a transformer, so that the voltage ratios are multiplied with an additional advantage of isolation.
