与连续控制方式相比较,开关控制方式的显著特点是当稳定输入电压变化比较大的非稳定电源稳定时,能获得非常高的效率。缺点是响应速度差,即输入电压突变或负荷电流突变时输出端容易产生过渡电压。为利用它的优点和避免它的缺点,作成连续控制和开关控制组合型实用化电源。 Compared with the continuous control mode, the remarkable characteristic of the switch control mode is that when the unstable input power is stable, the unstable power supply can achieve very high efficiency. The disadvantage is the poor response speed, that is, sudden changes in input voltage or load current sudden change when the output voltage transition prone. In order to take advantage of its advantages and to avoid its shortcomings, make a combination of continuous control and switching control of practical power.
