I am using ST's eDesign Suite to design a power supply. The suite helps with circuit, BOM and transformer design specifications.
I contacted the transformer design firm to get my transformer designed. I gave them all the information regarding the number of turns and length of wire etc.
They are asking me the polarity of the transformer and also the start and end pin connection of the winding.
Being an amateur in transformer design, I am unable to find any relevant information for the above query.
I need help with that.
Here are my power supply specifications:
- Input: 100 VAC - 265 VAC - 50 Hz
- Operating VDC [98.7 V - 374.8 V]
- Output Power: 14.96 W
- Out 1: 17 VDC (35 mVpp ripple) - 880 mA maximum - 14.96 W
- Switching Frequency (fsw): 60 kHz
