The figure below ia a suggested diagram to reduce Electromagnetic Interference (EMI). C1 = Electrolytic Capacitor Capacitance = 22uF - 220uF Voltage = Two times rated output voltage C1 = 0.22uF X Capacitor L1 = 3uH - 10uH C2, C3 = 220pF Y Capacitors C2 = Electrolytic Capacitor Capacitance = 22uF - 47uF Voltage = Two times rated output voltage Notes: C3 = Ceramic Capacitor Capacitance = 0.01uF - 0.1uF Voltage = 50 volt Notes: L1 = 10mH - 30mH Common Mode, Choke The diagram above is a recommended circuit, only by trying true application can levels be measured. Inrush Current If desired, the use of a Choke, NTC or Inrush Current Limiter may be used to reduce the Inrush Current 1. The use of C1 alone may reduce noise to desired levels, if not use L1, C2 and C3 in addition to C1. 2. The figure above is a suggested circuit. Only by trying true application can levels be tested.
