Description

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 (...)

Key Features

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