2. Single-phase generator - Wikipedia

   en.wikipedia.org/wiki/Single-phase_generator

   Elementary generator is an example of single-phase generators with two poles. Single-phase generator (also known as single-phase alternator) is an alternating current electrical generator that produces a single, continuously alternating voltage. Single-phase generators can be used to generate power in single-phase electric power systems.

3. 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 ...

4. Synchronization (alternating current) - Wikipedia

   en.wikipedia.org/wiki/Synchronization...

   During installation of a generator, careful checks are made to ensure the generator terminals and all control wiring is correct so that the order of phases (phase sequence) matches the system. Connecting a generator with the wrong phase sequence will result in large, possibly damaging, currents as the system voltages are opposite to those of ...

5. Rotary converter - Wikipedia

   en.wikipedia.org/wiki/Rotary_converter

   The self-balancing dynamo is of similar construction to the single- and two-phase rotary converter. It was commonly used to create a completely balanced three-wire 120/240-volt AC electrical supply. The AC extracted from the slip rings was fed into a transformer with a single center-tapped winding. The center-tapped winding forms the DC neutral ...

6. High-leg delta - Wikipedia

   en.wikipedia.org/wiki/High-leg_delta

   Current practice is to give separate services for single-phase and three-phase loads, e.g., 120 V split-phase (lighting etc.) and 240 V to 600 V three-phase (for large motors). However, many jurisdictions forbid more than one class for a premises' service, and the choice may come down to 120/240 V split-phase, 208 V single-phase or three-phase ...

7. Single-phase electric power - Wikipedia

   en.wikipedia.org/wiki/Single-phase_electric_power

   Single-phase motors may have taps to allow their use on either 208-volt or 240-volt supply. A single-phase load may be powered directly from a three-phase distribution transformer in two ways: by connection between one phase and neutral or by connection between two phases. These two give different voltages from a given supply.
