2. Grid-tie inverter - Wikipedia

   en.wikipedia.org/wiki/Grid-tie_inverter

   For smaller inverters for residential use, the output voltage is usually 240 VAC. Inverters that target commercial applications are available for 208, 240, 277, 400, 480 or 600 VAC and may also produce three phase power. Peak efficiency: The peak efficiency represents the highest efficiency that the inverter can achieve. Most grid-tie inverters ...

3. Power inverter - Wikipedia

   en.wikipedia.org/wiki/Power_inverter

   Modified sine wave produced by a cigarette lighter 12 volt DC to 120 V AC 60 Hz inverter. The modified sine wave is the sum of two square waves, one of which is delayed one-quarter of the period with respect to the other. The result is a repeated voltage step sequence of zero, peak positive, zero, peak negative, and again zero.

4. 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 ...

5. Split-phase electric power - Wikipedia

   en.wikipedia.org/wiki/Split-phase_electric_power

   Additionally, technical power systems pay special attention to the way the distribution system is grounded. A risk of using a balanced power system in an installation that also uses "conventional" power in the same rooms is that a user may inadvertently interconnect the power systems together via an intermediate system of audio or video ...

6. Three-phase electric power - Wikipedia

   en.wikipedia.org/wiki/Three-phase_electric_power

   Three-phase transformer with four-wire output for 208Y/120 volt service: one wire for neutral, others for A, B and C phases. Three-phase electric power (abbreviated 3ϕ [1]) is a common type of alternating current (AC) used in electricity generation, transmission, and distribution. [2]

7. List of railway electrification systems - Wikipedia

   en.wikipedia.org/wiki/List_of_railway...

   This is a list of the power supply systems that are, or have been, used for railway electrification. Note that the voltages are nominal and vary depending on load and distance from the substation. As of 2023 [update] many trams and trains use on-board solid-state electronics to convert these supplies to run three-phase AC traction motors.
