Bulk capacitance sizing is an important factor in motor drive system design. The amount of bulk capacitance depends on a variety of factors including:
The inductance between the power supply and motor drive system limits the rate that current can change from the power supply. If the local bulk capacitance is too small, the system responds to excessive current demands or dumps from the motor with a change in voltage. Size the bulk capacitance to meet acceptable voltage ripple levels.
The data sheet provides a recommended minimum value, but system-level testing is required to determine the appropriate-sized bulk capacitor.
