[Abstract]:High-end MOS drive circuit is widely used in high-voltage input power supply. In this paper, the driving principle of high end MOS tube is analyzed, the factors influencing the drive of high end MOS tube are discussed, and the basic method suitable for the drive of high end MOS tube is put forward. The influence of the traditional transformer drive circuit and bootstrap drive circuit on the high end MOS transistor drive is comprehensively evaluated. Then the circuit structure suitable for the high end MOS tube driving circuit is proposed and an experimental circuit is designed with this scheme. The simulation and experimental circuit test results show that the designed circuit meets the requirements.
