METHOD FOR OPERATING AN LLC RESONANT CONVERTER FOR AN ILLUMINANT, CONVERTER AND LED CONVERTER

摘要

An LLC resonant converter (19) for an illuminant (5) has a primary-side circuit (19) and a secondary-side circuit (30) galvanically isolated therefrom. When the LLC resonant converter (19) is in operation, a first switch (21) and a second switch (22) of a half-bridge circuit to which an LLC resonant circuit (25-27) of the primary-side circuit (19) is connected are switched cyclically. A voltage (V_sns) is detected in the primary-side circuit (19). The voltage (V_sns) detected in the primary-side circuit (19) is processed in order to obtain information about an output voltage of the secondary-side circuit (30).
