英訳例	コメント
The present invention achieves a high-efficiency power conversion device.	文法的にはOKですが、**"achieves"**は少し曖昧で、装置そのものを「実現する」というより「達成する」ニュアンスになりやすいです。技術文脈では不自然に感じられる場合があります。
The present invention enables the realization of a high-efficiency power conversion device.	よりフォーマルで特許文にありがちなスタイル。ただしやや冗長です。

✨ 解説：

• “provides” は特許で非常によく使われ、「〜を実現する」「〜を提供する」という日本語に対する最も一般的かつ自然な動詞です。

• “high-efficiency power conversion device” は直訳的ですが自然で、専門的な響きを保ちます。

あなた:

How about "realizes" or "obtains"?

ChatGPT:

Great question! Let's compare "realizes" and "obtains" with the commonly used "provides" or "achieves" in the context of:

“本発明は、高効率な電力変換装置を実現する。”

---

🔍 1. "realizes"

The present invention realizes a high-efficiency power conversion device.

✅ Grammatically correct?

Yes.

⚠️ Stylistic/technical evaluation:

• "Realize" is occasionally used in technical writing, especially in Japanese-English translations, but it’s less natural in English when the subject is "the invention".

• It tends to sound like "the invention has become self-aware" (especially outside of Japanese-influenced contexts).

• Native English-speaking engineers or patent attorneys typically avoid using "realize" in this way.

Verdict:

✔️ Acceptable but not recommended for formal patent or technical documents. Use sparingly.

---

🔍 2. "obtains"

The present invention obtains a high-efficiency power conversion device.

⚠️ Problematic:

• "Obtain" suggests receiving or acquiring something from outside.

• It does not match the intended meaning of “実現する,” which is more about achieving, creating, or enabling a result.

Verdict:

❌ Not suitable in this context.

---

✅ Best alternatives:

Verb	Example	Notes
provides	The present invention provides a high-efficiency power conversion device.	✅ Most natural and widely used in patents.
achieves	The present invention achieves high-efficiency power conversion.	✅ Good if you're emphasizing the result, not the device itself.
enables	The present invention enables high-efficiency power conversion.	✅ Suitable when the invention allows other things to accomplish the goal.
realizes	The present invention realizes a high-efficiency power conversion device.	⚠️ Acceptable but sounds awkward to native ears. Common in J-E translations.
obtains	—	❌ Not appropriate here.

---

🎯 Conclusion:

Stick with "provides" or "achieves" depending on whether you want to emphasize the device itself or the performance/result.
