Power module

A power module, comprising:

• a substrate comprising plural first conducting parts, plural second conducting parts and at least one third conducting part;
• at least one first sub-module disposed on the substrate, wherein each of the at least one first sub-module comprises a first semiconductor switch, a first diode, a first electrode, a second electrode and a third electrode, wherein the first semiconductor switch comprises plural first conducting terminals, and the first diode comprises plural second conducting terminals, wherein the first electrode and the third electrode are electrically connected with corresponding ones of the first conducting terminals of the first semiconductor switch and electrically connected with corresponding ones of the second conducting terminals of the first diode, and the second electrode is electrically connected with a corresponding one of the first conducting terminals, wherein the first electrode and the second electrode are contacted with corresponding ones of the first conducting parts, and the third electrode is contacted with the at least one third conducting part;
• and
• at least one second sub-module disposed on the substrate, wherein each of the at least one second sub-module comprises a second semiconductor switch, a second diode, a fourth electrode, a fifth electrode and a sixth electrode, wherein the second semiconductor switch comprises plural third conducting terminals, and the second diode comprises plural fourth conducting terminals, wherein the fourth electrode and the sixth electrode are electrically connected with corresponding ones of the third conducting terminals of the second semiconductor switch and electrically connected with corresponding ones of the fourth conducting terminals of the second diode, and the fifth electrode is electrically connected with a corresponding one of the third conducting terminals, wherein the fourth electrode and the fifth electrode are contacted with the corresponding one of the second conducting parts, and the sixth electrode is contacted with the third conducting part.
