ON Semiconductor Interview Questions and Answers

Transformers are electrical devices that transfer electrical energy between two or more circuits through electromagnetic induction.

• Transformers are used to increase or decrease voltage levels in electrical circuits.

• There are two main types of losses associated with transformers: copper losses and iron losses.

• Copper losses occur due to the resistance of the copper windings in the transformer and are proportional to the ...read more

Power loss in electrical systems can be categorized into core losses, hysteresis loss, and eddy current loss.

• Core losses occur in the magnetic core of transformers and include hysteresis and eddy current losses.

• Hysteresis loss is caused by the reversal of magnetization in the core material, leading to energy dissipation in the form of heat.

• Eddy current loss is caused by circulating currents induced in the core material...read more
