Title

Design of Quasi-Resonant Flyback Topology for wide range input

Authors

Abstract

A standard flyback converter that selects the best operating conditions among different control scheme (converter Load and Input voltage), to achieve minimum turn-on losses, low electromagnetic interference (EMI) emission, with short-circuit protection and optimized efficiency, is presented in this paper. The control schemes used are: Quasi Resonant mode, valley-skipping mode and Burst-mode. Quasi resonant mode takes place at heavy load or/ converter low input voltages. The converter operates close to boundary conduction mode (BCM) and continuous conduction (CCM). Valley-skipping mode operates at medium/ light load or converter medium input voltage. Externally programmable oscillator of Power IC L6566BH, synchronized to turn on MOSFET, operates at converter maximum frequency. Burst mode operates at no load or very light load or at converter high input voltage. This converter has unique advantage of operating either on fixed frequency mode or variable frequency mode depending on the wide range of input voltage and load.
