ABSTRACT:
The specification discloses a lightweight, compact welding transformer particularly well suited for robotic applications. The transformer includes coplanar secondary pads, a parallel common bus, and a secondary coil having turns each including a first end coupled to the common bus and a second end extending through the common bus and coupled to one of the secondary pads. The transformer further includes planar diodes abutting the secondary pads opposite the coil and a planar rectified bus abutting the diodes to sandwich them against the secondary pads.
