Abstract(E)	We propose a new 1.2-kV double-sided direct-cooling power module (PM) that uses high thermal conductive insulation sheets. This PM uses two new insulation technologies. The first is a conductor laminated insulation sheet that divides the void voltage inside the insulation sheet to improve a partial discharge voltage compared with a conventional sheet. The second is a new power terminal insulation structure that uses a high comparative tracking index transfer molding resin. This new structure achieves a narrow space design of high voltage DC terminals for reducing stray inductance and enables faster switching speeds. We evaluate the performance of the developed PM, and the results prove its lower thermal resistance and stray inductance performance.

About search

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.

If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).

Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.

Example) X AND Y → "X and Y (including)" X OR Z → "X or Z (including)"

If AND and OR searches are mixed, OR search has priority.

Example) X AND Y OR Z → X AND (Y OR Z)

If AND search and multiple OR search are mixed, OR search has priority.

Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.

The number in "()" after each item is the number of data that includes that item.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
