摘　　要：在众多开关电源设计书籍中,介绍电源稳定性问题时都局限小信号稳定性指标——相位裕度和增益裕度上。但实际情况是相位裕度和增益裕度都满足设计要求时,并不能保证电源产品在复杂的电特性组态和生产、试验及元器件参数离散条件下稳定工作。本文在提出了广义开关电源稳定性判据的前提下,从系统实际应用的角度出发,论述了电源产品在构成电源应用系统时需用遵循稳定性判定标准。遵照标准可以解决实际电源系统应用中的诸多疑难杂症,达到事半功倍的效果。Most books related to switch power supply design are usually limited to the small signal stability indices such as phase margin and gain margin when introducing problems of power stability. However, the fact is that even if both phase margin and gain margin meet the design requirements, the steady work of power supply products is still not ensured, under the conditions including complicated electrical property configuration and discrete parameters of production, testing and components. On the premise of introducing the stability criterion of generalized switch power supply, this paper, from the perspective of system actual application, discusses the stability criterion required to follow when the power supply products construct the power supply application system. Conforming to the criterion could solve a number of difficult problems in actual application, and then achieve multiple results with little efforts.
