Abstract
A stacked output structure of a capacitive power supply for welding equipment, having a plurality of capacitors to be connected in parallel, two electrodes of each capacitor are respectively provided with a pin including a long pin and a short pin; at least two PCB bus plates placed in stack are provided above the capacitor is provided. A lower PCB bus plate is connected with the short pin; and a pass-through hole is provided, at a position corresponds to the long pin, on the lower PCB bus plate. The long pin passes through the pass-through hole in the lower PCB bus plate and is connected with an upper PCB bus plate. There is a gap between the long pin and an inner wall of the pass-through hole.
