Claim of US Patent No. 9,907,199

1. A power electronic module comprising: a plurality of pairs of power electronic components each pair comprising at least
a first power electronic component and a second power electronic component which are identical, a first support and a second
support arranged approximately parallel to each other, the first support comprising a first electrical circuit and the second
support comprising a second electrical circuit,
the first power electronic component of each pair comprising a first face and a second face, the first power electronic component
of each pair being supported by the first face on the first support in electrical contact with the first electrical circuit
and being electrically connected to the second electrical circuit by the second face with a smaller thermal contact area than
a contact area between the first face and the first support;

the second power electronic component of each pair comprising a third face and a fourth face, the second power electronic
component of each pair being supported by the third face on the second support in electrical contact the second electrical
circuit and being electrically connected to the first electrical circuit by the fourth face with a smaller thermal contact
area than a contact area between the third face and the second support, the first power electronic component and the second
power electronic component of each pair having a redundant arrangement,

wherein the first power electronic component of at least one pair of the plurality of pair which comprises at least a first
control contact and at least a first power contact and a second power contact, the first control contact being located on
the second face of the first power electronic component of the at least one pair and at least the first power contact being
located on the first face of the first power electronic component of the at least one pair,

wherein the second power electronic component of the at least one pair comprises at least a second control contact and at
least a third power contact and a fourth power contact, the second control contact being located on the fourth face of the
second power electronic component of the at least one pair and at least the third power contact being located on the third
face of the second power electronic component of the at least one pair,

wherein the first electrical circuit includes at least one first high power circuit conducting track, and a first control
conducting track, the second electrical circuit including at least one third high power circuit conducting track, and a second
control conducting track,

wherein the first power electronic component of the at least one pair is arranged on the first support with the first power
contact of the first face in contact with the first high power circuit conducing track and with the first control contact
connected to the third control conducting track, and second power electronic component of the at least one pair is arranged
on the second support with the second power contact of the fourth face in contact with the first high power circuit conducting
track and with the third control contact connected to the first control conducting track.
