i rebuilt PCB follow new SCH, anyone help to advise
Thanks.
Hi H500
Thank for your help
I also receive a Kreutz’s comment in PM.
So I will update my schematic as below:
1. Add a .1u 16v cap to the power pin of each ir2184.
2. Add 33 ohm in series with...
Hi all,
PCB top and bottom for checking
Thanks
Hi all,
here is my schematic, pls help me how to modify schematic so that i can run with high voltage.
Thanks
Hi all,
Pls help me on this:
I’m DIY a 5 phase pentagon driver base on schematic at post#107 in this thread
I can not find out some part in my country so I replaced by others:
+ MOSFET driver:...
Hi H500,
Thank for your support, i will send file to PCB vendor soon.
Any problem during testing Driver,i will let you know.
Thanks.
Hi H500,
I will sent file to a PCB vendor when everything is OK,
my pcb was lacked heat-sink for mosfet, thank for your reminding. i never see Gecko driver, can you show me about heat-sink on...
Hi H500,
I modified PCB follow your comment, Pls check and advice one more time.
Thanks
Hi H500,
You commented about minimize the trace inductances from IR2104 to mosfet or from CPLD to IR2104 so i mean arangement trace from IR2104 to mosfet is the shortest.
Thanks.
Hi H500,
I finished PCB, pls help me give your opinion on PCB
I followed Mariss's document to drawing H-Bridge.
If you have Eagle cad-soft pls let me know then i will attached original file. ...
Hi H500,
Thank for your advice about diode
almost i use 0805 SMT component.
today is holiday so i will try to finish PCB and post to thread so that you help me give out opinion.
Best regards.
Hi H500,e
I enclosed schema, pls give your opinion.
Schematic has some differences with original design so my country don't have some components:
1. Replaced IRF530 by IRF540N.
2. Replaced BAS516...
Hi H500
Latch-up mosfet happen when CPLD don’t drive IR IC then Vgate of mosfet auto rise up high level and lead to shorted circuit at low side and high side mosfet, I met this problem in the past...
Hi H500,
Thank for great support,
I have just received 5 pcs XC2C64 in this afternoon. i am drawing PCB on eagle, i think i can finish on next week.
R17: i replaced by 1x16.9Kohms resistor +...
hi H500!
I haven’t built this circuit yet and trying to learn before building.
If you have working board, you can share PCB design experience about CPLD or any important note during design PCB, I...
Hi H500,
I don’t understand about “the advantage of low impedance and temperature compensation”. This is so strange for me, if you can pls share document about this then I try to study.
For the...
Hi H500,
I have some queries on your schematic, pls help me overcome this:
1. Can you explain about Q5, Q6, Q7 R27 and R19? This is complex for me. Can I change these components by a varistor and...
