TOPSwitch? Power Supply Design Techniques for EMI and Safety:Offline switching power supplies have high voltage and high
current switching waveforms that generate Electromagnetic
Interference (EMI) in the form of both conducted and radiated
emissions. Consequently, all off-line power supplies must be
designed to attenuate or suppress EMI emissions below
commonly acceptable limits.
This application note presents design techniques that reduce
conducted EMI emissions in TOPSwitch power supplies below
normally specified limits. Properly designed transformers, PC
boards, and EMI filters not only reduce conducted EMI emissions
but also suppress radiated EMI emissions and improve EMI
susceptibility. These techniques can also be used in applications
with DC input voltages such as Telecom and Television Cable
Communication (or Cablecom). Refer to AN-14 and AN-20 for
additional information. The following topics will be presented:
? EMI Specifications for North America, European
Community, and Germany
? Measuring Conducted Emissions with a LISN
? Peak, Quasi-Peak, and Average Detection Methods
? Safety Principles
? EMI Filter Components
? Flyback Power Supply EMI Signature Waveforms
? Filter Analysis
? Power Cord Resonances
? Transformer Construction Techniques
? Suppression Techniques
? General Purpose TOPSwitch EMI Filters
? EMI Filter PC Layout Issues
? Practical Considerations
