Transformer Diagram
| AUTO-TRANSFORMER. A transformer with only one winding. The secondary side [same winding] has two or more fixed taps or a movable tap and a common point with the primary. |  Autotransformer |
BALUN TRANSFORMER. Refer to the definition of Balun.
CORE. The material placed within a coil to intensify the magnetic field. Possible core materials include iron and even air cores.
COUPLING TRANSFORMER. A transformer used to couple or connect two different circuits. A coupling transformer may be a 1:1 winding transformer, a Step Up transformer or a Step Up transformer.
ISOLATION TRANSFORMER. A transformer used to isolate or decouple two different circuits. An isolation transformer could be used to prevent unwanted interaction between two circuits, block DC or electrically isolate different systems.
PRIMARY. The input side of a transformer. The primary side of a transformer connected to the electrical source. The primary transformer winding normally is used to set up current that is then transferred to one or more secondary windings of the transformer.
Transformer Symbols
SCHEMATIC SYMBOLS. The symbols used to represent a transformer on a schematic drawing. A number of transformer symbols are shown in the graphic above. A schematic diagram for a Step Up Transformer symbol using a different number of coil turns between the primary and secondary side is shown on the MIL-1553 Interface page.
SECONDARY. The winding on the output side of a transformer.
TRANSFORMER. A device composed of two or more coils, linked by magnetic lines of force, used to transfer energy from one circuit to another, at the same frequency but not always at the same voltage.
TRANSFORMER EFFICIENCY. The ratio of output power to input power, generally expressed as a percentage.
TRANSFORMER, STEP-DOWN. A transformer so constructed that the number of turns in the secondary winding is less than the number of turns in the primary winding. A Step Down Transformer is construction to provide less voltage in the secondary circuit than in the primary circuit.
TRANSFORMER, STEP-UP. A Step Up Transformer is constructed so that the number of turns in the secondary winding is more than the number of turns in the primary winding. This construction will provide more voltage in the secondary circuit than in the primary circuit. In many cases a Step Up Transformer Symbol will like just like a 1:1 transformer. However in a small number of cases a Step Up Transformer Symbol will show more windings on the secondary side than the primary side in the schematic.
TOROIDAL TRANSFORMER. A round shaped magnetic core with windings forming a transformer. The graphic shows a Toroidal transformer with dual winding wound around the same core.
TURNS RATIO. The ratio of the number of turns in the primary winding to the number of turns in the secondary winding of a transformer. The turns ratio indicates if the transformer is a step-up, step-down or 1-to-1 voltage change.
