Abstract: Disclosed are an asymmetric half-bridge converter and a control method therefor. By means of additionally providing a one-way clamping network connected in parallel with a primary side, a secondary side or a third winding of a transformer, when an excitation inductance current reaches a set value, an auxiliary switch is controlled to be switched off and the one-way clamping network is controlled to be conducted, such that a clamping current flows through the one-way clamping network, and the one-way clamping network performs clamping and keeps the camping current substantially unchanged; and within a period of time before a main switch is conducted, the one-way clamping network is controlled to be switched off in order to release the clamping current, such that the voltages at two ends of the main switch are reduced to zero or close to zero, thereby realizing zero-voltage conduction of the main switch. The present invention can realize effective control over a negative peak of an excitation inductance current, and reduces a current effective value of a power device under a light/no load of a converter; moreover, where the advantages of zero-voltage conduction of an existing technical solution are retained, the present invention greatly improves the light-load efficiency of the converter, reduces the no-load loss, and is simply and efficiently controlled.
