Abstract :
This paper presents an auto tuning system using a variable synchronous switched capacitor for controlling the resonant frequency of a half bridge voltage mode resonant converter. This original tuning topology does not need the addition of any bulky magnetic and consequently is naturally compatible with MRI (Magnetic Resonance Imaging) equipments.
