Design of the gate drive circuit for floating MOSFET using the pulse transformer

펄스 변압기를 이용한 비접지 MOSFET의 게이트 구동 회로 설계

This paper presents the new design method for the gate driver circuit of the floating MOSFET by using the pulse transformer. Each parameters of the proposed circuit are delivered by the numerical calculation method. By considering inner characteristics of MOSFET, the gate driver makes to increase the efficiency of the power conversion and decrease operating heat. Computer simulations and to experimental results for a Buck Converter are presented in order to validate the proposed method.
