Definition of transformer in English:



  • 1An apparatus for reducing or increasing the voltage of an alternating current.

    • ‘It is used for making relays, transformers, solenoids, current transformers, safety plugs for gas applications.’
    • ‘All pots, transformers and circuit board edge connectors mount to an internal subframe assembly.’
    • ‘One high voltage transformer that has something wrong with it.’
    • ‘LED lights require a transformer to turn alternating current to direct current.’
    • ‘A transformer boosted the tube voltage to about 50 000 V, and x-ray imaging was done by both fluoroscopy and photography.’
    • ‘Alternating voltage fed into a transformer - which is not a new development - will boost it to any voltage you want, with no moving parts.’
    • ‘He describes transformers as raising voltage ‘in something like the way that squeezing the end of a garden hose produces a more powerful jet of water’.’
    • ‘PCBs are colorless and odorless chemicals that were widely used in electrical equipment such as transformers and capacitors before 1977.’
    • ‘Fire bells sounded in response to an explosion in a high voltage power transformer in the hospital basement.’
    • ‘Remember, you can only plug mains voltage lighting into an external socket as low voltage lighting requires a transformer and currently most transformers are not suitable for outside use.’
    • ‘How do I check the output voltage of your electronic transformers?’
    • ‘The circuit keeps interrupting itself in this way, gradually boosting voltage through the transformer.’
    • ‘The transformer in the output stage simply increases the voltage by 10, thus producing approximately 90 volts AC.’
    • ‘Method and apparatus for a coherence transformer with limited memory for connecting computer system coherence domains’
    • ‘No or low output voltage means the transformer winding has open or shorted winding.’
    • ‘European machines, which operate on electrical standards different from those of U.S. machines, require transformers to step voltages up or down.’
    • ‘Stand at least two feet away from welding equipment, high-voltage transformers or motor-generator systems.’
    • ‘One solution is to contact the power utility company, get it to confirm the sag and retap the transformer to bring the voltage swing within an acceptable range.’
    • ‘The stable oily liquid, which absorbs intense heat, was used as a coolant for electrical transformers and capacitors.’
    • ‘Let's start with the heart of the circuit, the main transformer, the device that actually boosts the voltage.’
  • 2A person or thing that transforms something.

    • ‘He is known as a daring innovator in science, as an indefatigable researcher and as a great transformer of nature.’
    • ‘Earth is also the great transformer of chi often serving as a transition between two other elements.’
    • ‘He himself admires Peter the Great, the legendary but tyrannical transformer of 18th-century Russia.’
