Hey, I think its easy for u not for me, If it would have been easy I would not have asked for the help, right? so if u hve any idea please suggest me.pg_83in said:hey the project is easy enjoy
Hi, tahnks for the initial respone.narbeh_rob said:hi , i am new in EDA
try this on your prject
1) use isolated powersupply on power switching and control side.
2) use opto cuplers to isolate control signals form your power switching side.
if u still have a problem on your project i can help u .
narbeh_rob said:1) send me the H-bridge part number which u use.
2) if it is possible send me the schematic designed file of your project.
Hi. I have allready gone through the application note . I was not able to get the information about the MOSFETs which I should use. Along with it i am no able to understand how to get the 12v which was shown in application notes.narbeh_rob said:let me know if the application note help u.
fuzzzy said:Look at L620r for Hbridge driver or VNH3A totally integrated full bridge 30A form ST microelectronics. Also interesting IR3220 from IR International rectifier.
Actually I was trying to build my H-Bridge, VNH3A would be shortcut, If i wont be able to construct H-bridge I will try it. Anyways Thanks for your suggestions.kender said:fuzzzy said:Look at L620r for Hbridge driver or VNH3A totally integrated full bridge 30A form ST microelectronics.

I have tried VNH3 chip. It's indeed a simple solution for a motor drive problem. However, it has one caveat. The VNH3 chip has 3 pads on the uderside of the chip, which must be soldered for the chip to operate at all. This has to be done through oven soldering, becasue these 3 pads are not exposed.
I haven't used IR3220, but it seems that it can be soldered onto a board with just regular surfacemount soldering with the soldering iron.
Hi, could u suggest me the mosfets which I should use.narbeh_rob said:if the 12v is your problem to supply the chip , simply use DC-DC converter modules . (for example 80 to 12 (input side 80 v and output side is 12v))
Hi, Thank u very much for your help. Could u guide me about which optical encoder should I use to sense the dhaft angle of my motor. Please could u tell me how i am going to transfer the information to PIC.narbeh_rob said:the type of Mosfet is not your problem
u can easily select a mosfet which support the motor nature Current and also with Peak current 10 time bigger than that current
