That’s a good point. The fix for this should be simple enough though; just set a little dead time. Of course this may not even be an issue if the bridges switch close enough to each other. I tend to think if these bricks can be paralleled and share current with out any problems they should work here. We have to keep in mind that, during switching, these parts are liner devices so even if these was a slight time difference the error current between the two bridges may be relatively small due to the bridge impedance at the instant of overlap. I am ordering the driver boards today so we may have a definitive answer to this in the not to distant future.
