ตรงสุดท้าย ทีเขาเรียกlevel shift ความจริงมันคือการย้ายสัณญาณมาเทียบไฟลบ เพราะ ir2111 ทำทำงานแบบไฟบวกอย่างเดียว12v ก็เลยเอา0vของไฟเลียง2110มาเทียบลบ ฉะนั้นสัณญาณทีจะมาป้อน มันก็ต้องเทียบไฟลบด้วย ic ถึงจะทำงาน

It is not possible to get 10.000 W with that size.
This topology is very old. Today we can design class D easier. Class D is scalable but 10.000W need higher skill and new design
