<p>#CMT# #/CMT# The stack has electronic components stacked along a stacking axis, and end flanges (42, 44) connected with each other by tie rods (46) that are extended parallel to the axis. Rigid intermediate flanges (50, 52) are arranged in a current part of the stack for resuming transverse forces and defining elementary stacks formed of switching branches in the stack. Each intermediate flange includes holes for passage of the tie rods to assure recovery of the efforts. Ball joints (82, 92) are interposed between each intermediate flange and an end of the elementary stack. #CMT#USE : #/CMT# Electronic components e.g. insulated gate bipolar transistors and diodes, stack for a high power electrical installation. #CMT#ADVANTAGE : #/CMT# The intermediate flanges assure recovery of the efforts on the tie rods so as to reduce buckling of the stack, so that a large number of power electronic components are arranged successively in a same stack as the components are connected or not connected in series, thus reducing weight and volume of the installation. The ball joints assure homogeneous distribution of pressures in the stack on entire cross-section of semi-conductor components. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a functional schematic view of a mechanical part of a stack. 42, 44 : End flanges 46 : Tie rods 50, 52 : Rigid intermediate flanges 70, 72 : Force distribution wedges 82, 92 : Ball joints.</p> |
