Check the motor’s power, voltage, and required power factor. Use the formula or an online capacitor sizing calculator.
What determines the size of a bulk capacitor?
The higher the capacitance, the lower the deviation. Therefore, the size of the input bulk capacitor is determined by the size of the output current transient and the allowable input voltage deviation. The amplitude of the input voltage deviation during a transient is directly proportional to the load current change.
How to calculate capacitance of a capacitor?
