一、引言开关稳压器通常指相对于串联调整稳压器的串联线性调整元件工作在开关状态。在一些文献资料中把开关稳压器称为“断续式稳压器”、“脉冲稳压器”等。就其基本工作原理和实际电路不论叫法如何都是一样的。开关稳压器与串联调整稳压器比较,具有许多显著的优点。迅速发展起来的宇航技术,对电子设备电源缩小体积、减轻重量、提高效率、提高可靠性诸方面已提出越来越高的要求。而开关稳压器正具有上述优点,尤其在低压大电流输出情况下,特点更为显著。近年来随着功率开关元件的进展和实验技术的提高,开关稳
I. INTRODUCTION Switching Regulator usually refers to the series linear regulator relative to the series regulator regulator work in the switch state. In some literature, switching regulators are referred to as “chopper regulators”, “pulse regulators” and the like. Its basic working principle and the actual circuit no matter how the law is the same. Switching regulators and series regulator regulator compared with many significant advantages. The rapid development of aerospace technology has raised increasing demands for reducing the size of electronic equipment supplies, reducing weight, improving efficiency and enhancing reliability. The switching regulator is having these advantages, especially in the case of low-voltage high-current output, the more significant features. In recent years, with the progress of power switching components and experimental techniques to improve, switch stability
