THREE-PHASE CIRCUIT APPLICATION
Remark:
Output filtering capacitors C1,C3 is electrolytic capacitors, It is
recommended to use high frequency and low impedance electrolytic
capacitors. Recommended value (C1:220µF/10V; C3: 100µF/25V); C2, C4
are ceramic capacitors and they used to filter high frequency noise,
Recommend value:0.1µF/50V , It is recommended that the 5.3V main
output circuit adds TVS to protect post-circuits (if converter fails),;and the
12.6V main output circuit has had TVS inside so it needs no external TVS.
