Frequently asked questions
- What happens when you suddenly disconnect an inductor from a circuit?
- The inductor tries to maintain its current, generating a large voltage spike ('inductive kick'). This is why flyback diodes are used across relay coils and motor drivers to protect switching transistors.
- How is inductor energy used in switching power supplies?
- In a buck or boost converter, the inductor stores energy during one switch phase and releases it during the other, allowing efficient voltage conversion.
