In accordance with the maximum energy of a short-circuit and the request of maximum output voltage ripple, this paper calculates the spectrum value of the output filter capacitor and provides its design and procedures to determine the parameters of the main circuit of power supply. The correctness and availability of this theory are eventually validated by experiments.}, type={Article}, title={Design of quasi-resonant flyback secondary intrinsically safe power supply}, URL={http://www.czasopisma.pan.pl/Content/109910/PDF/AEE-68-1-2019_art_1.pdf}, doi={10.24425/aee.2019.125976}, keywords={intrinsic safety, secondary power supply, quasi-resonant technology}, }
