Intro to ECSE Analysis

2. Outline
Transformers & Coupled Inductors
The Three Transformer Laws

3. The Three Laws Voltage Ratio Current Ratio Input Impedance
Resistances must be small compared to the inductive impedances

4. LTspice Simulation

5. Validity of Three Laws Check resistance vs inductive impedance
Clearly satisfied for 10kHz. Even better for larger inductance values.

6. Coupled Inductors
