Complete Electronics Self-Teaching Guide with Projects

Summary and Applications

In this chapter, you learned about the following topics related to transformers:

• The principles that allow an AC signal to be induced in a secondary coil
• How the AC voltage across the secondary coil can be stepped up or down depending upon the turns ratio of the transformer
• The use of a center tap to produce various voltages from a transformer
• The use of transformers to match impedances between a generator and a load
• That transformers can cause the output signal to be inverted (out of phase) from the input signal
