hi all!
Sorry for my English.
This is my first post in this forum, I'm also interested to make this SMPS project, please help to avoid future missteps, and therefore there are some questions that are still confusing me
, it is:
1. If I do not find the right core, what alternative instead?. I have a core with size (/ - L * H * W) 49 * 27 * 17mm, what can be used?
2. I have two sizes of wire, 0.1mm and 0.4mm, which is suitable for the core?
3. If they fit or can be used, how the turn and strand should I make to the primary side and secondary side?, In this case the target is a symmetrical output +-75V /and +-50V.
4. What transformers are used to supply the SG and IR?, Could use a non-sealed transformer or from the main transformer? and why?
5. Can someone explain about the details Current transformer? (About cores are used, the wire size, number of turns, the jumper through current transformers, etc.).
6. In PWM circuit there are two trimmer (R12 & R13) and there is another one in the protected module (R5), what is its function?, And how to set it? ...
7. What is the total value of micro (u) capacitor (min) for each output rails?
8. What is the minimum value of amperes at Relay?
9. What kind of load used to test this project?, Maybe a lightbulb? Minimum or maximum number of Watt or the Ohm?
10. What about efficiency, the normal temperature of the FETs with or without a load, and can i see the complete scheme of this project as a reference source?
Thank you.:UP:
