摘要： A system and method to ensure the proper operation of a power supply unit in an electronic device. The electronic device has a chassis with a length and a width that includes one area having electronic components. A system fan is located in the chassis relative to the electronic components to generate air flow in the direction of the length of the chassis through the electronic components. A power supply unit is located in parallel to the system fan relative to the width of the chassis. The power supply unit includes an AC input, a DC output and an internal fan. A controller is operable to control the system fan to reduce the air flow when the power supply unit turns on AC power to the AC input, or wakes up from a cold redundant state and outputs DC power from the DC output.

摘要： The present invention concerns a protective cover (400) designed to cover power, filtering and control modules of an electronic assembly for a rotating electric machine for a motor vehicle. Said protective cover (400) is characterised in that it comprises:—openings (401, 402, 403, 404) designed to generate different cooling air streams (F1, F2, F3, F4) for heat dissipation requirements of each of the power, control and filtering modules;—the openings of the protective cover (400) being distributed into: a first set of openings (401) designed to be positioned facing the fins of a first heat sink coupled to the power module; a second set of openings (402) designed to be positioned facing the control module; the two sets of openings (401, 402) being separated by a barrier wall (405) so as to create a first radial cooling air stream (F1) for said power module and a second radial cooling air stream (F2) for said control module; and a third set of openings (403) designed to be positioned facing the fins of a second heat sink coupled to condensers of the filtering module so as to create a third radial cooling air stream (F3) for said filtering module.

摘要： Disclosed herein is an assembly structure for a motor drive unit. An assembly structure for a motor drive unit is disclosed. The assembly structure does not require the time for rotating, laying down, or fastening the components during processes of producing it, so that the time required for production can be shortened. In addition, since no separate fastening part is required, the assembly structure can be simplified and the production costs can be reduced.
