摘要：

This paper introduces a new resonant gate driver for both the top and bottom switches of a synchronous buck converter. A coupled inductor is used to reduce the size as well as to transfer energy between the top and bottom gate driving. A possible semiconductor integration approach is proposed for this resonant gate driver based on a self-adaptive control method. Theoretical analysis, simulation and experimental results prove that the proposed driver can greatly reduce the gate driving loss and that it is well suited to high-frequency applications.
