| Abstract: | In the use of loosely coupled transformer for power transmission,The work frequency of the system and component selection are close with the capacity of the power transmission system.In this paper,given to analysis the application of the loosely coupled transformer in the flyback switching power supply,And the voltage and current waveforms of the primary side and secondary side of loosely coupled transformer are analyzed in time domain.The moment of secondary side conduction and shut off are determined.This thesis has the intuitive judgment on the feasibility of the system and provides the basis for component selection. |
