5. CONCLUSION
It is concluded that the new circuit implementation of replacing the inductor (L2) and changing
the RSENSE (R4) fully function as expected. As configured in a high-power 48V LED module,
the efficiency is about ~88% and PFC is ~0.969. As configured in a high-power 96V LED
module, the efficiency is about ~87.6% and PFC is ~0.962.
Main benefits are achieved in the high-power LED evaluation:
1) High Efficiency
2) High PFC (>0.9)
3) No electrolytic capacitor
4) Correct average LED output current
5) Suitable for E27 LED Light Bulbs
