Wireless energy transmission system based on multi-tube alternation

The invention relates to a wireless energy transmission system based on multi-tube alternation, which belongs to the technical field of electronic equipment and structurally comprises a direct current conversion module (1), a wireless energy conversion module (2), a wireless energy transmitting module (3) and a wireless energy receiving module (4). The structure of the wireless energy conversion module (2) comprises a time sequence generation module (21), a time sequence distribution module (22), an upper bridge driving array (23), a lower bridge driving array (24) and an MOS tube array (25). According to the invention, the working time of each field-effect tube in the array can be shortened to a quarter of the original working time under the condition of not changing the technical index of the AC voltage source of the output port, and the heating phenomenon of the field-effect tubes when the system operates under the long-time working condition or the high-power working condition is improved. 本发明的一种基于多管轮替的无线
