I usually see that smoothing or filter capacitors used after rectified mains, consist of two, or more capacitors in parallel. For example, it''s common in treadmills to find two 1500 uF capacitors in parallel instead of using just one of 3000uF or 3300uF (more common). Is there any advantage of this when it comes to electrical/electronics issues?
