  2. Voltage converter - Wikipedia

    en.wikipedia.org/wiki/Voltage_converter

    The output will usually be DC in the range 1.5–24 V. Power supplies that output either 100–120 V AC or 210–240 V AC are available; they are called inverters, due to the conversion from DC to AC rather than the voltage change. The output frequency and waveform of an inverter may not accurately replicate that supplied by mains electricity ...

    en.wikipedia.org/wiki/Electric_power_distribution

    By contrast, direct-current indoor incandescent lighting systems, such as Edison's first power station, installed in 1882, had difficulty supplying customers more than a mile away because they used a low voltage (110 V) from generation to end use. The low voltage translated to higher current and required thick copper cables for transmission.

  4. Constant-voltage speaker system - Wikipedia

    en.wikipedia.org/wiki/Constant-voltage_speaker...

    Similarly, in a constant-voltage speaker system, the amplifier uses a transformer to step up the voltage of the audio signal to reduce power loss over the speaker cable, allowing more power to be transmitted over a given wire diameter. Each speaker in the system has a step-down transformer to reduce the voltage to a usable level.

    On the three secondary terminals, the center tap is grounded with a short strap to the transformer case. A split-phase or single-phase three-wire system is a type of single-phase electric power distribution. It is the alternating current (AC) equivalent of the original Edison Machine Works three-wire direct-current system. Its primary advantage ...

  9. Distribution transformer - Wikipedia

    en.wikipedia.org/wiki/Distribution_transformer

    A distribution transformer or service transformer provides a final voltage transformation in the electric power distribution system, stepping down the voltage used in the distribution lines to the level used by the customer. [1] The invention of a practical, efficient transformer made AC power distribution feasible; a system using distribution ...
