6 FAQs about [Do you need a high frequency energy storage inductor ]
Can high frequency inductors miniaturize power electronics?
Operation in the high frequency (HF) regime (3{ 30 MHz) has potential for miniaturizing power electronics, but designing small, e cient inductors at HF can be challenging.
