Zusammenfassung:	The invention discloses a self-adaptive novel soft switching full-bridge circuit driving method and a full-bridge driving circuit. The full-bridge driving circuit comprises a full-bridge circuit, wherein the full-bridge circuit is composed of a first switching device, a second switching device, a third switching device and a fourth switching device. A first external control signal is connected with the third control end of the third switching device, and a second external control signal is connected with the fourth control end of the fourth switching device; a first node is arranged on a connecting circuit located between the first switching device and the third switching device, and a second node is arranged on a connecting circuit located between the second switching device and the fourth switching device; the first control end of the first switching device is connected with the second node, the second control end of the second switching device is connected with the first node, and the first node is connected with the second node through a load loop with the inductance feature. The self-adaptive novel soft switching full-bridge circuit driving method and the full-bridge driving circuit have the advantages that the circuit is simple, the zero-voltage and zero-current soft switching function can be conveniently fulfilled, and the circuit layout is flexible.
