Well, not as balanced. This all depends on the speed of the signals you are switching and the length and width of traces. Very fast signals are going to be more unbalanced then very slow signals, and very large currents are going to be more unbalanced than very small currents. In your drawing...
B equalizes resistance seen by each diode so they will carry like currents assuming they are matched for forward voltage. C will result in higher resistance as you move out from the central connection. The diodes further away from the center will carry less current due to the larger resistance...
The SMPS has limits as to the supply rails be driven above the rated output voltage and below ground. At a minimum you will want to stay within those limits, as well as current draw. When the motor starts up there will be a large current spike. When you shut the motor off you will get a large...
What are the power ratings of the motor ? Do you reverse the motor rapidly ? I am dealing with a DC 12 volt motor, 250 watt. Reversing control via H Drive. The peak currents at points of reversal have been measured near 50 amps for 20 ns. Dropping rapidly to quiescent levels of a few amps...
