I kindly request you to refer the design file of 75W LED driver using PIEXPERT tool by refering reference
design document RDR290 for street light application. And i selected Power LED of Vf=3.3 with IF.typical=700mA
and IF.max=1.5A connecting 30nos. of LED's in series to reduce the output current for better thermal performance therefore
driver output voltage is selected 100VDC and output current 750mA.
Selecting PQ32/30 transformer core design is not optimized. Designing a prototype board using same
schematic and optimization can be done or please suggest any changes to be done in the schematic.
waiting for you reply
