hi PI expert
thank you very much of your last help it was helpfull.,
about di-66 project
1-please introduce me what is CTR(current transfer ratio) in
optocouplers and is it important parameter? and tell me some
optocouplers instead of PC817C because i did not find it but
PC817B and PC817 is available?
2- about MBR20100CT, it has two diode inside it,>i should use just one
of them or i must connect both anode together and use it in circuit?
3-what is the volatge and current of bias winding in di-66 ?
4-what is the volatge and current of "C" pin of TOP246Y?
5-what is the volatge and current of "F" pin of TOP246Y?
6-can i use R=150kohm from "12V output" to "reference pin of LM431"
to improve crossover regulation?
7- i used 3.5uH instead of 3.3uH for L2 & L3,is it important?
8-i used two 1Mohm & 0.25 watt instead of 2Mohm 0.5Watt,please tell me
your opinion?
Thank you
Adel
