升压式开关直流调压器的不变性控制法

An Invariant Control Method for Step-Up Switching D.C.Regulators

本文提出并分析了升压式开关直流调压器的一种不变性控制方法，它允许电源电压和负载电流在一定范围内变化而不影响输出电压值，而且该调压器的工作频率恒定。

An invariant control method for step up switching D.C.regulators was proposed and analyzed in this paper.Using this control method,the step up D.C.regulator will work with constant frequency.Besides,the supply voltage and the load current of the regulator may vary in a certain region without changing its output voltage.Conclusions of example calculations were given.
