摘要
针对电力设备对直流供电电源的要求,采用可以有效抑制输出电压纹波与输出电流谐波的双脉宽调制方式为开关管的控制方法,在此基础上对采用该技术的DC-DC电源设计进行了研究。首先完成电源的方案设计,并对电源控制系统进行详细的理论分析与计算,最后通过对设计电源的动态响应速度、抗输入扰动能力与抗负载突变能力等指标的实验,对电源的设计方案进行验证。
In view of the requirement of DC power supply for power equipment,a switching control method based on double-pulse width modulation which can effectively suppress the output voltage ripple and output current harmonics is adopted.Firstly,the design of the power supply is completed,and the power control system is theoretically analyzed and calculated in detail.Finally,the design scheme of the power supply is verified through experiments on the indicators such as the dynamic response speed of the design power supply,the ability to resist input disturbance and the ability to resist load mutation.
