Coupled Circuits
OBJECTIVES
In this chapter you will learn about:
- The need for coupling
- Classification of coupled circuits
- Performing calculations based on M = k√L1L2
- Response of different types of coupled circuits
- The effect of variations of coupling elements
- Mutual coupling
- Reflected impedance and its importance
Transfer of energy through magnetic couplings: (loose, critical and tight coupling)
30.1 INTRODUCTION
When the interaction between two loops of a circuit takes place through a magnetic field instead of through common elements, the loops are said to be inductively or magnetically coupled. The windings of a transformer, for example, ...
