PROBLEM TO BE SOLVED: To provide an electric power conversion system which achieves downsizing of a physical constitution while inhibiting electromagnetic wave noise caused by transformers T1 to T8 from reaching switching elements Q1a to Q8a and Q1b to Q8b.SOLUTION: An electric power conversion system 1 includes: converters 30, 40; inverters 50, 60; and a heat sink 80. Switching elements Q1a to Q8a are installed on an upper surface 83 of the heat sink 80. Switching elements Q1b to Q8b are installed on a lower surface 84 of the heat sink 80. Transformers T1 to T8 are embedded in the heat sink 80. Thus, the heat sink 80 is disposed between the switching elements Q1a to Q8a, Q1b to Q8b and the transformers T1 to T4, T5 to T8. |
