Felicitamos al estudiante, ya graduado, de doctorado Josué Lara Reyes por la publicación de un artículo más resultado de su tesis de doctorado. Muchas felicidades Josué!
The main contribution of this paper is to show the analysis and design of a resonant converter which was designed to operate in the transient stage and with underdamped response, where the resonant network stage has a frequency equal to “n” times the frequency of the switching stage (fsw) “fo = nfsw”. The main advantage of this design methodology is to be able to operate the converter with frequencies higher than 1 MHz in the resonant network stage, without obtaining high levels of losses in the inverse stage. To validate this design methodology, a full bridge resonant converter acting as a frequency multiplier was implemented for a low power wireless power transmission application. For the experimental tests, a base frequency of 300 kHz was decided in the inverting stage, with a frequency multiplication of n = 3, 5, 7 in the resonant network stage (900 kHz, 1.5 MHz, 2.1 MHz) for an output power of 12 watts. Experimental tests proved the operation of the converter acting as a multiplier, where it was possible to reduce losses in the inverter stage, achieving efficiencies of up to 93% in the switching stage with frequencies higher than 1 MHz.
