Development of a half-bridge LLC DC-DC loaded resonant converter for low power application / Mazliza Abdul Halim

An LLC DC-DC loaded resonant converter is gaining more attention in power-supply designs due to its potential to achieve high efficiency and power density. Due to complex resonant circuit behaviour, the design method of LLC converter becomes complicated and difficult. In the past, there are many stu...

Due to complex resonant circuit behaviour, the design method of LLC converter becomes complicated and difficult. In the past, there are many studies have presented the design methods of LLC converter to facilitate the design work.
