The value of the blocking capacitor (C) depends on the application conditions and defines voltage and
current ripple onto supply line at PWM operation. Stored energy of the motor inductance may fly back
into the blocking capacitor, if the bridge driver goes into tri-state. This causes a hazardous overvoltage
if the capacitor is not big enough. As basic orientation, 500µF per 10A load current is recommended.
