Design of Driving Power Supply for Vibration Aging Device Based on IGBT

随着大功率振动时效装置的发展,基于超磁致伸缩材料的激振器被用作振动时效装置的振动机构,需要设计新的驱动电源以满足装置对驱动电流、频率的要求。针对既有振动时效装置中超磁致伸缩激振器驱动电源存在的缺陷,基于双环控制思想,采用IGBT和PWM技术设计一种包括主电路、控制电路和采集电路的驱动电源,使输出的直流电压精度高且稳定可调,驱动激振器按照给定的控制信号进行工作。测试结果证明了所设计的驱动电源的合理性和有效性。

Aiming at the defects of the driving power supply of giant magnetostrictive exciter in the existing VSR device,a driving power supply including main circuit,control circuit and acquisition circuit is designed by using insulated gate bipolar transistor and PWM technology based on the idea of double-loop control.The output DC voltage is high precision and stable,and the driving exciter works according to the given control signal.The test results prove the rationality and validity of the designed driving power supply.
