prof. Sam Ben-Yaakov in his video shows practical example of use of variable controlled inductor in LLC converter application example.
The variable inductor has been shown to be useful in resonant converters, LED drivers, APFC and many others.
Let’s have a look into why variable inductor use can be beneficial in LLC converter application:
- Possibility to operate at fixed frequency
- Wider operational range
- Can improve soft switching
- Possibly higher efficiency
