Transformer
Specifications
Primary and Secondary Coil Inductance
Primary and Secondary Turns (NP or NS)
Equivalent Series Resistance (ESR)
Load Regulation
• Since transformers have inherent ESR,
changes in load current may
cause problems
• Varies almost
linearly
Shielding
• Unshielded
transformers create mutual inductance with other materials
and are also the source of EMI
