Note:

1. C1,C2and C3 are electrolytic capacitors. They are required both AC input and DC input.

The value of C1 is recommended to be 4.7μF /400V . When the input voltage is above 370VDC, the recommended value of C1 is 4.7μF/450V).C2 and C3 are

output filer capacitors, they are recommended to be high frequency and low impedance electrolytic capacitors. Capacitance and rated ripple current of

capacitors refer to the datasheets provided by the manufactures. Voltage derating of capacitors should be 80% or above. C4 is a ceramic capacitor, which is

used to filter high frequency noise. C2,C3 and L1 form a pi-type filter circuit. Current of L1 and L2 refer to the datasheets provided by the manufactures, current

derating should be 80% or above. TVS is a recommended component to protect post-circuits (if converter fails).
