  2. Polarity (mutual inductance) - Wikipedia

    en.wikipedia.org/wiki/Polarity_(mutual_inductance)

    A transformer is called "additive" if, conceptually, connecting the high-voltage terminal to the adjacent low-voltage terminal gives a total voltage between the other two terminals that is the sum of the high voltage and low voltage ratings, when the high-voltage winding is excited at rated voltage. The H1 and X2 terminals are physically adjacent.

  3. Current transformer - Wikipedia

    en.wikipedia.org/wiki/Current_transformer

    A current transformer has a primary winding, a core, and a secondary winding, although some transformers use an air core. While the physical principles are the same, the details of a "current" transformer compared with a "voltage" transformer will differ owing to different requirements of the application.

    Transformer: sometimes changed to "L" for inductor TUN: Tuner: U, IC: Integrated circuit (IC) shorter "U" (unit) is preferred instead of "IC" V: Vacuum tube: VR: Voltage regulator (voltage reference), or variable resistor (potentiometer / trimmer / rheostat) voltage regulators are often "U" for IC, pots and trimmers often "R" for resistor X

  5. Transformer - Wikipedia

    en.wikipedia.org/wiki/Transformer

    In electrical engineering, a transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits.A varying current in any coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force (EMF) across any other coils wound around the same core.

  6. Instrument transformer - Wikipedia

    en.wikipedia.org/wiki/Instrument_transformer

    The primary winding of the transformer is connected to the high voltage or high current circuit, and the meter or relay is connected to the secondary circuit. Instrument transformers may also be used as an isolation transformer so that secondary quantities may be used in phase shifting without affecting other primary connected devices. [1]

  7. Equivalent impedance transforms - Wikipedia

    en.wikipedia.org/wiki/Equivalent_impedance...

    Darlington gives an equivalent transform that can eliminate an ideal transformer altogether. This technique requires that the transformer is next to (or capable of being moved next to) an "L" network of same-kind impedances. The transform in all variants results in the "L" network facing the opposite way, that is, topologically mirrored. [2]

    The nation's largest bank earned $14 billion in the final quarter of 2024 due largely to a Wall Street revival, pushing its annual haul to an all-time record of $58 billion.

  9. Diffusion model - Wikipedia

    en.wikipedia.org/wiki/Diffusion_model

    For example, the diffusion transformer (DiT) uses a Transformer to predict the mean and diagonal covariance of the noise, given the textual conditioning and the partially denoised image. It is the same as standard U-Net-based denoising diffusion model, with a Transformer replacing the U-Net. [54] Mixture of experts-Transformer can also be ...
