2. Introduction
• • What is EMI?
• • What is EMC?
• • Why are they important in electrical and
electronic systems?
3. What is EMI?
• • Definition: Unwanted electromagnetic
energy that interferes with device operation
• • Sources: Natural (lightning, solar flares),
Man-made (motors, radios, switching devices)
• • Types:
• - Conducted EMI
• - Radiated EMI
4. What is EMC?
• • Definition: The ability of equipment to
operate properly in its electromagnetic
environment
• • Goals:
• - Limit emissions
• - Increase immunity
• • Importance in device compliance and
reliability
5. Types of EMI
• • Narrowband vs Broadband
• • Continuous vs Transient
• • Examples: Power lines, radio signals,
switching transients
6. EMC Standards & Regulations
• • International Standards:
• - CISPR
• - IEC
• - ISO
• • Regional Standards:
• - FCC (USA)
• - EN Standards (Europe)
• - BIS (India)
• • Role of regulatory bodies
7. EMI Sources in Electrical Systems
• • Switching power supplies
• • Electric motors
• • High-frequency circuits
• • Wireless communication systems
8. Effects of EMI
• • Data loss
• • Malfunctioning of medical or defense
equipment
• • Communication disruption
• • Safety risks
9. Methods of EMI Mitigation
• • Shielding
• • Filtering
• • Grounding
• • PCB layout design
• • Use of ferrite beads and chokes
10. EMC Testing
• • Emission Testing: Measures how much EMI a
device emits
• • Immunity Testing: Checks how well a device
resists EMI
• • Lab environment and test setups
11. EMI/EMC in Product Design
• • Design considerations from the beginning
• • Material selection
• • Enclosure design
• • Signal routing and isolation
12. EMI/EMC Case Studies
• • Example 1: EMI in automotive systems
• • Example 2: EMC failure in consumer
electronics
• • Lessons learned
13. Conclusion
• • Summary of key points
• • Importance of EMI/EMC in modern
electronics
• • Future trends: IoT, EVs, and 5G challenges
