Note:
For standard EMC requirement, please refer to figure 1 , if higher EMC requirement ,please refer to figure 3.
1.
C1:AC input, is filtering electrolytic capacitor (which is required), when input voltage is below 100VAC, and the value of C1 is 22μF/400V.
DC input, is a filtering capacitor in EMC Filter, the value of C1 is 10µF/400V(when input voltage is above 370VDC, and the value of C1 is 10µF/450V), If
EMC performance is not required,C1 could not need.
2.
C2 is ceramic capacitor, it is used to filter high frequency noise. Output filtering capacitor C3 (which is required when AC input or DC input) is recommended to
use high frequency and low impedance electrolytic capacitors. For capacitance and current of capacitor please refer to manufacture’s datasheet. Voltage
derating of capacitor should be 80% or above. TVS is a recommended component to protect post-circuits (if converter fails).
