Abstract
A method for estimating an output voltage of an isolated resonant converter is disclosed. The proposed method, wherein the isolated resonant converter includes a transformer having an auxiliary winding and a secondary winding, a first output diode electrically connected to the secondary winding in series and a voltage holder coupled to the auxiliary winding, includes: obtaining the output voltage where v(t) is an output voltage of the voltage holder, Vis a forward voltage drop of the first output diode, Nis a number of turns of the secondary winding and Nis a number of turns of the auxiliary winding.
