Abstract(J)電気自動車の電気部品の小型化・低コスト化・高効率化が求められる中,駆動用モータおよびインバータを活用した充給電統合ドライブユニットを検討した.巻線の直列・並列切替により高出力と高効率駆動を両立するとともに,AC充電時のトルクレス化と充電効率の両立が可能であることを示した.

Translation

Abstract(E)As electric vehicles incorporate a large number of electrical components, there is a growing demand for miniaturization, cost reduction, and high efficiency. In this study, an integrated charging and power supply drive unit utilizing a traction motor and inverter is investigated. By switching the motor windings between series and parallel configurations, both high power and high-efficiency drive operation are achieved. Furthermore, torque-free operation during AC charging and high charging efficiency are simultaneously realized.

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.
