D.C. power unit assembly including unitized single-phase D.C. power units

A D.C. power unit assembly comprising:

• a plurality of D.C. power units each having a planar rectified pad and a common terminal, said planar pads being coplanar;
• a flat common bus overlying and spaced from said planar rectified pads, said common bus being parallel to said planar pads;
• a pair of flat rectified buses overlying said planar rectified pads, each of said rectified buses being parallel to said planar pads, said rectified buses being spaced from one another throughout their lengths, said common bus being located directly between and spaced from said rectified buses, whereby said common bus and said rectified bus present a low profile with respect to said pads;
• first means for electrically connecting each of said common terminals to said common bus;
• and
• second means for electrically connecting each of said pads to each of said rectified buses.

A D.C power unit assembly comprising:

• a plurality of D.C. power units each including a rectified pad for conducting rectified current, each rectified pad having first and second opposite ends, said first ends being located in a first area and said second ends being located in a second area, each D.C. power unit further including a common terminal;
• a common bus overlying and electrically insulated from said pads, said bus being located between said first and second pad ends throughout its length;
• a rectified bus assembly having first and second bus portions on opposite sides of said common bus;
• first means for electrically connecting each of said common terminals to said common bus;
• and
• second means for electrically connecting each of said first and second rectified pad ends to said first and second rectified bus portions, respectively.
