The invention relates to a power electronics and electric energy conversion circuit, and aims to provide an isolation type high-frequency low-loss driving circuit. The isolation type high-frequency low-loss driving circuit comprises MOSFETs which are simplified to be switching tubes M; each driving circuit also comprises a square wave power supply, a resonant inductor, a primary winding and a first secondary winding, wherein the square wave power supply, the resonant inductor and the primary winding are connected in series; one end of the first secondary winding is connected to the gate pole of each switching tube M while the source electrode of the switching tube M is connected to the other end of the first secondary winding; and the primary winding and the first secondary winding are wound around the same magnetic core to form a transformer T1. According to the isolation type high-frequency low-loss driving circuit, capacitance resonance is input through the resonant inductor and the gate pole of the switching tube, so that the voltage on parasitical capacitor is sine waveform, and therefore, the driving of the switching tube is realized, and recycling of driving energy is also achieved, thereby reducing driving loss; in addition, the gate pole voltage can be clamped through a clamping winding, so that damage to the switching tube caused by an overhigh gate pole voltage can be prevented; and by adopting a way of increasing the secondary windings, driving of multiple switching tubes can be realized.
