In the convergence–confinement method, the longitudinal deformation profile (LDP) serves as a graphical representation of the actual tunnel convergence (both ahead of and behind the face); therefore, it is considered important for determining the d

A Constant Current Digital Control Method for Primary-Side Regulation Active-Clamp Flyback Converter
Publikováno v:
IEEE Transactions on Power Electronics. 36:7307-7318
Constant current controlled flyback converter is widely used in low power applications for its simple structure and low cost. In order to further improve the output power and the efficiency, active-clamp flyback converter with soft-switching techniqu
