Figure 1 A classic LM317 constant current source where: Iout = Vadj/R = 1.25v/Rs. Figure 2 shows another (easier) way to make Iout programmable. The circuit enables control of ampere-scale Iout with ...

Figure 1: Comparison between conventional and PT-symmetry-based wireless power transfer schemes as the source–receiver resonant coupling rate κ varies as a function of transfer distance d ...
