Power conversion apparatus

A power conversion apparatus comprising:

• a first power converter driving a first electric load by switching-control of a plurality of first semiconductor elements, and
• a second power converter driving a second electric load by switching-control of a plurality of second semiconductor elements,
• said plurality of first semiconductor elements being organized into a plurality of first semiconductor element groups, each first semiconductor element group including at least one first semiconductor element,
• said plurality of second semiconductor elements being organized into a plurality of second semiconductor element groups, each second semiconductor element group including at least one second semiconductor element,
• said first power converter being a first inverter carrying out power conversion between a power supply and said first electric load, each of said plurality of first semiconductor element groups constituting an arm of each phase in said first inverter,
• said second power converter being a second inverter carrying out power conversion between said power supply and said second electric load, each of said plurality of second semiconductor element groups constituting an arm of each phase in said second inverter,
• said plurality of first semiconductor element groups being arranged in alignment in a first direction on a substrate, and at least some of the first semiconductor element groups adjacent in said first direction being arranged displaced from each other in a second direction perpendicular to said first direction, and
• said plurality of second semiconductor element groups being arranged in alignment in said first direction on said substrate, and at least some of the second semiconductor element groups adjacent in said first direction being arranged displaced from each other in said second direction and to be adjacent to said first semiconductor element group along said first direction.
