Abstract :
An industrial multi-output QRC converter is presented. Its main design constraints are low cost, small size, reduced EMI and EMC, high efficiency and severe dynamic behaviour in all outputs. Accomplishing this last restriction proved to be a difficult task. This has been done by means of a classical controller and cross regulation. The actual performance was tested on a 1 MHz prototype rated at 50 W. The low cost developed converter is characterized by its simplicity of design and operation, yet is versatile in performance. Actual experimental results are presented
