开关电源系统稳定性补偿电路的设计

Design of Stability Compensation Circuit for Switching Power Supply

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．

An open-loop stability for a switching power supply usually is undesirable.Therefore its stability has to be designed so that it is able to run safely and reliably.In this paper,we study the problem and give a frequency-domain method used for design stability compensation circuits.An exemplification shows that it is correct and valid.
