  23. APPENDIX

  24. Why PF Correction ? • Power company unhappy • Large power loss ( input current increase) • Reduce current harmonic distortion • Neutral Wire Burns(potential fire hazard) • More limitation on wall socket output • For example:120V,line 12Arms (Household Regulation) • then Max.=1.4KW Output • if PF=0.6 then Max. power=0.84KW

  25. BROWN OUT TEST

  26. What is CE ? • CE=EMC+Safety(TUV or VDE) • EMC=EMI+EMS • EMI=Conduction +Radiation • EMS • ESD(Electrostatic Discharge):air 15KV,contact 8KV • EFT(Electrical Fast Transient):level 4,4KV • RS(Radiated Susceptibility):Level 3,10V/m • CS(Conducted Susceptibility):Level 3,3V/m • Surge/Lightning :Level special 6KV • Current Harmonic:<5%

  27. Why Soft-Switching(ZVS,ZCS) ? • Reduce switching loss • Increase switching frequency • Reduce EMI noise • Increase Switch Component SOA Ids Vds

  28. Because the CE Mark is mandated for all products shipped into the European Union, it has become the driving force for standards harmonization world-wide The CE Mark

  29. What is Electrostatic Discharge A person or charged object discharging into a sensitive electronic component or circuit can cause a device to fail or circuit to be upset.

  30. The threshold of feeling is 2kV to 4kV. Everyone can feel 5kV. 15kV is a memorable event! What is Electrostatic Discharge

  31. Arcing, which occurs as a switch opens, is both conducted and radiated into sensitive electronic circuits. What is an Electrical Fast Transient ?

  32. High energy transients resulting from lightning or switching operations in the power system. What is a Surge ?

  33. AC Magnetic fields are created whenever current is flowing in a loop or through inductors - most commonly, electric motors and transformers. AC Magnetic Fields
