2. Voltage converter - Wikipedia

   en.wikipedia.org/wiki/Voltage_converter

   A simple voltage dropper can be used to reduce the voltage for low-power devices; if more than 12V is required, or for high-powered devices, a switched-mode power supply is used. 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 ...

3. National Grid (New Zealand) - Wikipedia

   en.wikipedia.org/wiki/National_Grid_(New_Zealand)

   In 1997, Transpower adopted a strategy known internally as “the glide path”, and minimised spending on the grid and renewing assets. The rationale for this strategy was based on the expectation that there would be widespread installation of distributed generation (electricity generated close to where it is used), and that this would significantly reduce the need to expand and renew the grid.

4. HVDC Inter-Island - Wikipedia

   en.wikipedia.org/wiki/HVDC_Inter-Island

   The New Zealand Inter-Island HVDC link is a long distance bipolar HVDC "Classic" transmission scheme that uses overhead lines and submarine cables to connect between the South and North Islands. It uses thyristor -based line-commutated converters at each end of the link for rectifying and inverting between AC and DC.

5. Phase converter - Wikipedia

   en.wikipedia.org/wiki/Phase_converter

   An American Rotary Phase Converter with a Transformer. A phase converter is a device that converts electric power provided as single phase to multiple phase or vice versa. The majority of phase converters are used to produce three-phase electric power from a single-phase source, thus allowing the operation of three-phase equipment at a site that only has single-phase electrical service.

6. Switched-mode power supply - Wikipedia

   en.wikipedia.org/wiki/Switched-mode_power_supply

   The inverter stage converts DC, whether directly from the input or from the rectifier stage described above, to AC by running it through a power oscillator, whose output transformer is very small with few windings, at a frequency of tens or hundreds of kilohertz. The frequency is usually chosen to be above 20 kHz, to make it inaudible to humans.

7. List of power stations in New Zealand - Wikipedia

   en.wikipedia.org/wiki/List_of_power_stations_in...

   Graph of New Zealand electricity generation capacity by year. This is a list of power stations in New Zealand. The list is not exhaustive – only power stations over 0.5 MW and significant power stations below 0.5 MW are listed. Power plants in New Zealand have different generating roles – for baseload, intermediate or peaking.
