Note:
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 flyback into the blocking capacitor, if the bridge driver goes into 3-state. This causes a
hazardous overvoltage if the capacitor is not big enough. As basic orientation, 500 µF per 10 A load current is recommended.
