Switching Power Supply Design Optimization By Sanjaya Maniktala Pdf Direct

Optimization begins with understanding that the inductor does not "store" energy in the way a battery does, but rather processes it. Maniktala argues against arbitrary inductance values. Instead, he promotes setting the inductance based on a target current ripple ratio ($r$).

Maniktala gives you the physics of failure:

Optimization of the input filter to meet CISPR/FCC standards without killing efficiency. 4. Component Stress and Reliability
