Beschreibung
Zusammenfassung:	The invention discloses a low-voltage stress wireless energy transmitting device for realizing soft switching by utilizing third harmonics. The device comprises a power supply VDD, a choking inductorLC, a switching tube S, a parallel capacitor CS, a resonant capacitor C0 and a transmitting coil L0. The choking inductor LC and the switching tube S are connected in series between the two ends of the power supply VDD, and the choking inductor LC h is located between the positive electrode of the power supply VDD and the switching tube S. The parallel capacitor CS is connected with the switchingtube S in parallel. The resonant capacitor C0 and the transmitting coil L0 are connected in series and are connected with the switching tube S in parallel. The device is characterized in that the device also comprises a clamping circuit and a third harmonic loop; the clamping circuit comprises a clamping capacitor CC and an auxiliary switch tube Sa; the clamping capacitor CC and the auxiliary switch tube Sa are connected i
