本文用状态空间平均法推导反激开关稳压系统的开环传递函数,并举例计算该系统的Bode 图,分析稳态占空比变化时对该系统Bo(?)e 特性和系统稳定性的影响,并与正激开关稳压系统的稳定性进行了比较。
In this paper, the open-loop transfer function of the flyback switching regulator system is deduced by means of state-space averaging method. The Bode graph of this system is given as an example to analyze the characteristics of Bo (?) E and the system stability when the steady-state duty cycle changes Influence, and compared with the stability of the forward switching regulator system.
