EMI EMC test standards? How MOV works? Power Supply Design?

Question

Accepted Answer

EMI EMC test standards are used to ensure that electronic devices meet electromagnetic compatibility requirements. MOVs are voltage-dependent resistors that protect against voltage surges. Power supply design involves creating efficient and reliable power sources for electronic devices.

EMI EMC test standards are used to evaluate the electromagnetic compatibility of electronic devices.
These standards specify the maximum allowable levels of electromagnetic interference (EMI) that a device can emit and the maximum levels of electromagnetic susceptibility (EMS) that it can tolerate.
Common EMI EMC test standards include CISPR, FCC, and IEC standards.
MOV stands for Metal Oxide Varistor, which is a voltage-dependent resistor.
MOV devices are used to protect electronic circuits from voltage surges or transients.
When the voltage across an MOV exceeds its threshold, it starts conducting and diverts the excess current away from the protected circuit.
MOV devices are commonly used in power supplies, surge protectors, and electronic equipment.
Power supply design involves creating efficient and reliable power sources for electronic devices.
It includes selecting appropriate components, designing voltage regulation circuits, and ensuring proper grounding and noise filtering.
Power supply design considerations include efficiency, voltage regulation, ripple and noise suppression, and protection against overvoltage and overcurrent.
Examples of power supply designs include linear power supplies, switching power supplies, and battery chargers.
