AI Technical Summary

Problems solved by technology

Certain extreme operating conditions such as overdrive or use at excessively high ambient temperatures may cause damage to one of these power components
This damage renders the device inoperable at all, and the resulting over- or under-excitation can prove dangerous in applications such as tunnel smoke extraction, power supplies to hospitals, or cooling pumps for nuclear reactors

Abstract

An electronic device (1), in particular a variable speed drive or alternator regulator, comprises at least one power component mounted on a heat sink (10) and a plurality of capacitors extending through at least one opening of the heat sink, characterized by the fact that it comprises a reinforcement in which a sealing gasket, in sheet form, is received, being applied on an inner face of the heatsink and on an opposite inner face of a casing connected to the heat sink, the inner faces of the heat sink and the casing coming into contact.

Description

technical field [0001] The present invention relates to electronic equipment including power stages such as variable speed drives or regulators. Background technique [0002] A variable speed drive or regulator is a device used in conjunction with an industrial motor or alternator to control the speed or voltage of the industrial motor or alternator. [0003] These devices typically include power components such as IGBTs or MOSFETs mounted on a heat sink, as well as relatively large electrochemical capacitors. [0004] The trend is to try to reduce the space requirements of these devices. [0005] Many solutions have been proposed for this purpose. [0006] Application US2014 / 0198455 discloses a variable speed drive comprising power components mounted on a printed circuit board and capacitors arranged at 90° to the board. [0007] Application US2010 / 0202109 discloses a device in which a capacitor is arranged close to the heat sink and through the opening of the cooling ai...
