Talk:H-bridge

From Wikipedia, the free encyclopedia

I must be tired, because it seems that the arrows showing current flow are actually drawn backwards in the 2 states of the H bridge drawing.

Does anyone else concur?

Anyway good article, thanks to the authors for their contributions.

Well... I as far as I can see, the arrows indicate the voltage, not the current... CyrilB 08:34, 8 November 2006 (UTC)

I'm pretty sure its backwards. 75.74.112.76 20:10, 18 November 2006 (UTC)

It would be backward if the arrows were representing the current, but it is the voltage ! CyrilB 19:38, 19 November 2006 (UTC)

[edit] An arrow indicates current

Any time I have seen an arrow in a schematic it has represented current. To represent voltage a "+" on one side and "-" on the other is the convention. Very often they will be shown together such as: + -------> - (looks better if the arrow is a straight line rather than a bunch of minus signs).

Also in addition to MOSFETs and BJTs, IGBTs can be used in H-bridges.

Usually, the arrows that indicate current are directly on the wires, not on their side. And I put what looks like a clear label to me (V). Furthermore, in most applications, a H bridge imposes the voltage to the load, not the current, so it is not possible to presume the direction of the current in the figures of the article, while it is for the voltage. If you have an idea to make the circuit more clear, please help yourself! Usually, the direction of the voltage arrows is from minus to plus (- --------> +).

And yes, IGBT can be used too, as any other switch (e.g. relays) CyrilB 10:53, 10 February 2007 (UTC)
