Abstract(J)	電気自動車に搭載されている電動パワートレインシステムは，電池の直流電流を電力変換装置であるインバータにより三相の交流に変換し，これをモーターに供給し駆動力とするシステムである．インバータやモーターの小型・高出力・高性能化が，電気自動車の電費改善に有効である．これには，これら製品に用いられている高機能樹脂の，耐熱性能や絶縁性能の向上が重要である．本稿では，電動パワートレインシステムの高性能化に貢献する高性能樹脂を概説する． Translation
Abstract(E)	The electric powertrain system used in electric vehicles uses a battery, an inverter, and a motor. The inverter converts the DC current into three-phase AC current, which is then supplied to the motor for driving power. The miniaturization, higher output, and higher performance of these components will improve the electricity cost of EV. It is important to improve the heat resistance and insulation performance of the functional polymer materials used in these products. This paper outlines the high-performance polymers that contribute to the high performance of electric powertrain systems.

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".
