I have prepared radio components, except for inductance, I will install them this weekend...
1. I'll pick up some kind of inductance from used...Ok
1> You will try an indoctor like -> THIS <- or -> THIS <- ?
2> For the Schottky diode you will use the SS36 model ?
3> You didn't tell me my capacitors in photo could be suitable or did a choose another models ?
1. No inductance is suitable, because they pass through a very weak current of 30mA and 110 mA.
Your calculations are correct!@ v1adpetrov2
Hello
Here is my reflexion about the inductor value for the regulator LM275 HVS-12:
Based on datasheets ->
View attachment 242577
I may have forgotten something or misinterpreted graphic...
This would give that with the references from MOUSER ->
What do you think ?
Yes, the voltage was 42V.View attachment 242600
Did you make a voltage reading at the input of this 'modified assembly' with the power supply set to 42V amp on ?
"The above formula yields capacitor values between 10 μF and 2000 μF that will satisfy the loop requirements for stable operation. But to achieve an acceptable output ripple voltage, (approximately 1% of the output voltage) and transient response, the output capacitor may need to be several times larger than the above formula yields". |
You need a proper eraser. A Staedtler Mars Plastic and a proper pencil and you could clean up your drafting skills immensely. Doing calculus and that sort of stuff is way easier with a nice pencil like this one. The numerals and symbols stay clear and defined and look real nice. Just saying because you are like almost 100% there in your handwritten drafting stuff.Your opinion ?
Take it by getting your coordinator to order in those items and enjoy! lol.
