Abstract(J)PHEVとEVはモーターを駆動させるための高出力インバーターを必要とする。モーターの回転スピードとトルクはそのインバーターの出力とスイッチング周波数に依存する。そのためインバーターとモーターの協調設計は車両性能に大きく影響する。今回は国際標準言語であるVHDL-AMSを用いて上記を可能とするモデルを作成した。

Abstract(E)PHEV and EV need a high-power inverter circuit for driving the e-motor. The motor rotational speed and torque depend on the swiching frequency and power from the inverter. Therefore, it’s important to adjust the specifications of the inverter together with those of the e-motor to optimize the vehicle performance.
In this project, we created an EV simulation model with the VHDL-AMS (a international standard language) and connected it to a battery, inverter, ECU, and motor model. The simulation model was also used to adjust the parameter of power devices and estimate the efficiency of the inverter circuit.

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.
