2. Push–pull converter - Wikipedia

   en.wikipedia.org/wiki/Push–pull_converter

   Push-pull converter (+12V → ±18V; 50W) as potted module. ① transformer; ② and ③ electrolytic capacitors vertical and horizontal mounted; ④ discrete circuit board in through-hole technology A push–pull converter is a type of DC-to-DC converter , a switching converter that uses a transformer to change the voltage of a DC power supply.

3. Delta-wye transformer - Wikipedia

   en.wikipedia.org/wiki/Delta-wye_transformer

   A delta-wye transformer is a type of three-phase electric power transformer design that employs delta-connected windings on its primary and wye/star connected windings on its secondary. A neutral wire can be provided on wye output side. It can be a single three-phase transformer, or built from three independent single-phase units.

4. Distribution transformer - Wikipedia

   en.wikipedia.org/wiki/Distribution_transformer

   A "transformer bank", widely used in North America: three single-phase transformers connected to make a 3-phase transformer. The low-voltage secondary windings are attached to three or four terminals on the transformer's side. In North American residences and small businesses, the secondary is often the split-phase 120/240-volt system. The 240 ...

5. Transformer types - Wikipedia

   en.wikipedia.org/wiki/Transformer_types

   A planar transformer Exploded view: the spiral primary "winding" on one side of the PCB (the spiral secondary "winding" is on the other side of the PCB) Manufacturers either use flat copper sheets or etch spiral patterns on a printed circuit board to form the "windings" of a planar transformer, replacing the turns of wire used to make other ...

6. Flyback transformer - Wikipedia

   en.wikipedia.org/wiki/Flyback_transformer

   The transformer can be equipped with extra windings whose sole purpose is to induce a relatively large voltage pulse when the magnetic field collapses as the input switch is turned off. There is considerable energy stored in the magnetic field, and coupling it out via extra windings helps it to collapse quickly, and avoids the voltage flash ...

7. DIP switch - Wikipedia

   en.wikipedia.org/wiki/DIP_switch

   A slide-style DIP switch soldered into a printed circuit board (PCB) Schematic symbol for each individual switch. A DIP switch is a manual electric switch that is packaged with others in a group in a standard dual in-line package (DIP). The term may refer to each individual switch, or to the unit as a whole.
