Power Supply Decoupling
... The inductor used must also be able to pass the direct current required by the circuit without saturation. A second capacitor, such as those shown dashed in Fig. 4-18, can be added to each section to increasing filtering to noise being fed back to the power supply from the circuit. This turns the fi ...

Superposition and Thevenin Theorems notes
... Thevenin’s Theorem. There are rare occasions when the application of Ohm’s law and the laws of series/parallel circuits make it extremely difficult or impossible to solve an electronic circuit. For these rare cases a man called Thevenin developed a theorem that can simplify a circuit to a single vo ...

Accurate Measurement of the Air-Core Inductance of Iron
... inrush currents, ferroresonance, and geomagnetic-induced currents [1]). However, it is not easy to measure in the field or laboratory because a very large ac power source (more than 10 times larger than the transformer rating) is needed. This is so because high voltage is needed to push the core int ...
