High-performance Switching Power Supply and Drive Design of the Middle and Small Wind Power System Converter

摘要

This paper describes the design of the soft-switching power supply and driver for wind power generation system converter, the reliability and stability of the switching power supply and driver of converter determine the security and reliable operation of the entire wind power generation system, thus increasing the efficiency of switching power supply, reducing switching losses and switching noise and increasing drives reliability is particularly important [1], this paper, which is based on the switching power supply control IC AN8026 and photo coupler PC929, design the switching power supply and drivers board of converter, the experimental results show that the soft switching power supply which is designed by AN8026 can improve the efficiency of switching power supply; the driver circuit based on photo coupler PC929 can increase the reliability of the converter driver, and safeguard the security and reliable operation of the wind power system, the switching power supply and driver board designed by this paper is especially fit for the middle and small wind power system converter hardware system design.
