【Abstract】 A frequency controller for wireless power supply based on DSP is designed. TMS320LF2407 is used as the main control chip and IR2110 is used as the power driver. It adapts SPWM as the method of DC/AC, the main loop current feeding back composes a closed loop, which controls the frequency of energy, thereby the wireless energy is efficiently passing, and the simulating result is given.更多还原
