Different Types Of Transformer | Electrical Darwaza

A transformer is a device working on mutual inductance principle to convert electrical energy from one voltage/ current level to another. There are different types of transformers used for different purposes.

(1) POWER TRANSFORMER

• Laminated core Transformer

• Toroidal Transformer

• Auto transformer
• Variable auto transformer

• Induction regulator Transformer(high voltage transformer)

• Polyphase transformer

• Grounding transformer
• Phase-shifting transformer
• Variable-frequency transformer(three-phase transformer)

• Leakage or stray field transformers

• Resonant transformer
• Constant voltage transformer
• Ferrite core transformer
• Planar transformer

• Oil cooled transformer

• Cast resin transformer
• Isolating transformer

(2) Instrument transformer

• Current transformer

• Voltage transformer or potential transformer
• Combined instrument transformer

(3) Pulse transformer

(4) RF transformer

• Air-core transformer
• Ferrite-core transformer
• Transmission-line transformer
• Balun transformer

(5) IF transformer

(6) Audio transformer

• Two speaker level audio transformer

• Five speaker level audio transformer

• Loudspeaker transformer

Output transformer

• Small signal transformer
• Inter stage and coupling transformers

Other types of transformers are

• Hedgehog transformer
• Rotary transformer
• Variable differential transformer
