【Abstract】 In the wireless power transfer(WPT) system, the maximum power point tracking(MPPT) system plays an important role in dynamic matching and improving the output power. In this paper, the perturbation observation method(P&O) is accelerated and improved based on the variation of the derivative of the output power with respect to the control voltage, for the maximum power point tracking of wireless energy transmission system. Compared with the traditional perturbation observation method based on fixed uniform step length, the improved method in this paper can increase the tracking speed by about 40%.更多还原
