Abstract(E)	This study proposes an integrated strategy to improve the electrical efficiency of electric compressors in electric vehicles (EVs), focusing on improvements in both motor design and inverter control. Key optimizations were applied to stator and rotor parameters, along with advanced inverter control techniques such as MTPA, DPWM, and SiC MOSFET integration. Additionally, a novel loss-based heating control method was explored to support heat pump operation under cold ambient conditions. Experimental validation confirms the effectiveness of the proposed approach, demonstrating its potential for improving EV energy consumption and system-level thermal management.

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".
