1. A power electrical device, comprising:
a first electrical module forming a power electronics module,
a second electrical module forming a power electronics module,
a third electrical module forming a capacitor module which comprises a plurality of electrical components and a casing, and
a cooling system comprising:
at least one fluid inlet and at least one fluid outlet for conveying and discharging a cooling fluid to and from the cooling system, respectively,
a first cooling module, comprising at least one cooling fluid circulation channel configured to cool said first electrical module,
a second cooling module, comprising at least one cooling fluid circulation channel configured to cool said second electrical module, and
a cooling circuit connection portion that connects said first cooling module and said second cooling module and is configured to fluidically connect said first cooling module to said second cooling module,
said first and second cooling modules being positioned on either side of said third electrical module,
said first and second cooling modules each having a portion that extends beyond and overhangs one and the same lateral face of said third electrical module, said portions facing one another and defining, with said lateral face, a free volume, and said first cooling module and said second cooling module each having a cooling circuit opening that leads into said free volume, said free volume accommodating said cooling circuit connection portion, said cooling circuit connection portion connecting said openings that lead into the free volume, and
wherein said first cooling module and second cooling module are interposed between the first electrical module and the third electrical module and between the third electrical module and the second electrical module, respectively.
