Abstract
A high-power semiconductor module having a casing which encloses at least one semiconductor element has an explosion protection element. This explosion protection element is a protective sheath which surrounds at least a portion of the casing and traps fragments which are projected outward in the event of an explosion of the semiconductor element. This prevents people from being injured or adjacent modules from being damaged by such fragments.
Claims14
A high-power semiconductor module, comprising:
- a casing which surrounds at least one semiconductor element, said casing having an explosion protection element for protection against fragments projected outward in the event of an explosion of said semiconductor module, wherein said explosion protection element comprises a protective flexible tube-shaped sheath made from fabric for trapping said fragments, said sheath surrounding at least a portion of said casing and comprising an expandable material.
The high-power semiconductor module assembly comprising:
- a plurality of modules which are stacked one above the other and are surrounded by a common protective sheath wherein at least one of said modules comprises a casing which surrounds at least one semiconductor element for protection against fragments projected outward in the event of an explosion of said module, wherein said explosion protection element comprises a protective flexible tube-shaped sheath made from fabric for trapping said fragments, said sheath surrounding at least a portion of said casing and comprising an expandable material.
A high-power semiconductor module comprising:
- a casing which surrounds at least one semiconductor element, said casing having an explosion protection means for protection against fragments projected outward in the event of an explosion of said module, wherein said explosion protection means comprises a protective flexible tube-shaped sheath made from fabric for trapping said fragments, said sheath surrounding at least a portion of said casing and comprising an expandable material.
The high-power semiconductor module assembly comprising:
- a plurality of modules which are stacked one above the other and are surrounded by a common protective sheath wherein at least one of said modules comprises a casing which surrounds at least one semiconductor element for protection against fragments projected outward in the event of an explosion of said module, wherein said explosion protection means comprises a protective flexible tube-shaped sheath made from fabric for trapping said fragments, said sheath surrounding at least a portion of said casing and comprising an expandable material.
