I have an 110 VDC motor , and i need to build a h-bridge for this motor if anyone have schematics to build or and suggestion or help


thanks

Using one MSK 4227 200 Volts 20 Amps hbridge already assembled with Individual Logic Level Gate Drive Inputs
should solve your problem.

See datasheet at this link

Goto mskennedy site and contact them to check if they sell direct or if they have a distributor near your place.

thanks for replies,
If one can help me to build this H-bridge using Mosfets and transistors ?
I need your help

I still think that you should use a ready made hbridge but if you want to try to build it yourself, you can use two IR2148 (low/high side driver) to activate the N-chan & P-chan power mosfet.
Read the datasheet to learn how to build the hbridge. You can download it @:

I suggest you to use fuses and start experimenting at low voltage and low current to learn how easily the hbridge can be shorted.

iugmoh,
I agree with Al 100%!
The article I posted is only to shoe you how to build a bridge and some of the problems with doing so.
