In view of such disadvantages as wire friction, aging and sparks produced during the transmission of electric energy in the traditional transmission system, a design has been proposed of the phase-shifted full-bridge DC converter. A physical isolation of the input and output can be realized by using the magnetically coupled resonant wireless transformer. Combined with phase-shift double closed loop control, a soft switching can be realized and the response speed can be increased. The designed converter and simulation can be realized by using Matlab / Simulink and TMS320F28335. Experiments show that the designed phase-shifted full-bridge magnetically coupled resonant wireless DC converter shows its advantages: faster in response while small in loss. In addition, the safety performance of the equipment can be improved by power transmission through a wireless transformer.
