本文提出了一种基于开关电源原理的极低纹波电源的设计方案,该方案不仅克服了线性电源体积大、效率低等致命弱点,同时还能够将输出纹波控制在极低水平.%This paper put forward design plan of power supply with extra-low ripple based on switched-mode power supply principle. Not only does the design overcome the vital shortcomings of linear power such as large volume, low efficiency. but also controls the output ripple in extra-low level.
