ON-BOARD POWER CONVERSION DEVICE Russian patent published in 2020 - IPC H02M7/48 H05K7/06 H05K7/20 

FIELD: electrical equipment.

SUBSTANCE: invention relates to the electrical equipment. On-board power conversion device includes housing (10), which forms locating section (11) for arrangement of excitation unit, which converts and transmits electric power (smoothing capacitor (20), power module (30)). Plurality of electric buses (40) connect input/output parts (part (51) of terminal leads on side of accumulator, part (52) of contact leads on side of electric motor) to/from which electric power is input and output, with excitation unit (smoothing capacitor (20), power module (30)) of housing (10). Electric buses (40) (the first electric bus (41), the second electric bus (42), the third electric bus (43)) contain heat dissipating sections (411), (421), (431), which are arranged along housing (10) with the possibility of heat transfer into housing (10) outside placing section (11).

EFFECT: reduced dimensions and increased structural flexibility of the device.
