Beschreibung

A SEPIC converter is used to fast charge a load capacitor up to 160V/180V (selectable). The input voltage range is 47V +/-10% and the constant output charging current 900mA. The SEPIC topology has the advantage to Boost or Buck the output voltage, needed by capacitor charging, since they start at zero volt (short circuit).

Eigenschaften

Remarks: Schematic and BOM is added with Test procedure PDF

No spikes on the drain of main FET, thanks to SEPIC topologyGood efficiency curve (>91%) at full load and with output voltage >80VTwo active loops: CV and CC stabilize the output voltage in all conditions, during charging and in steady stateThe output voltage can be switched between 160V and 180V on the fly
