开关电源系统的开环稳定性通常不高，甚至不稳定，因此，为使其安全可靠的工作必须进行稳定性设计．本文讨论了该问题，并给出了一种设计稳定性补偿电路的频域方法．一个设计实例表明：用本方法解决开关电源系统稳定性设计问题是行之有效的．
Open-loop stability of switched-mode power supply system is usually not high, or even unstable, therefore, in order to make its safe and reliable work must be stability design. This paper discusses the problem and gives a frequency-domain method for designing a stability compensation circuit. A design example shows that it is effective to solve the stability design of switching power supply system with this method.
