CASE ANALYSIS

Scenario

A small DC wind turbine feeds a fused buck converter that steps variable turbine voltage down to charge a 12V battery, which then powers a switched cabin LED light.

Key decisions

  • Use a buck converter with freewheeling diode and output capacitor for regulated 12V battery charging
  • Add input fuse and blocking diode to protect against overcurrent and reverse discharge
  • Connect LED lamp through an SPST switch for cabin lighting control

When to reuse this

Reuse for off-grid small wind turbine charge controllers where DC turbine output must be regulated before battery charging and a low-voltage DC load is switched separately.
