Since you have two on at any given time, you are hit with a (4V * 3.5A) or 14 Watt penalty right off the bat, and you haven't added switching losses.Īlso, the parts count goes WAY up. The transistors you've chosen come with a penalty: They will at best give you a 2V drop since they are Darlingtons. Using FETs gives you absolutely the most efficient bridge. Then what type of circuit would you recommend? I have to use the BDV66B and Is this because you already purchased them? Or did your instructor say to use Bipolars? Includes schematics and circuit examples. Learning how to use power MOSFETs by building an H-bridge motor control. H-Bridge Motor Control Using Power MOSFETS Your previous comments that don't consider the OP's request for 24V and Bipolar transistors make me wonder who is even silly enough to follow your advice that you just copied from another web site anyway. The fact that you don't and aren't willing to research it yourself causes me no loss of sleep.
Please Google it and understand it before your feeble attempt to SLAM me. I'm sure anyone that's ever designed an H-Bridge and attempted to run same above 15Khz understands "shoot through". As I've said from the start, a newbie has no business attempting to design an H-Bridge. If you are not going to explain this feature with a schematic, then don't bring up the subject because you are alone in your I doubt I am having a one way conversation.
You may select a product family from the table or scroll down for more information.ġ The TReX motor controllers have two bidirectional channels and one auxiliary unidirectional channel.Ģ Please see individual product pages for specific voltage and current ranges.ģ Please see individual product pages to see which specific controllers have enclosures.Otherwise you are having a one way conversation, citing concepts that nobody else is familiar with. The table below shows the key features and specifications of our motor controllers.
