The converter includes a ripple-filtering inductor, a power isolating and converting unit, a power switch, a first inductor, a first capacitor, a second capacitor, and a rectifying switch. The power isolating and converting unit comprises windings for isolation an input stage connected to a power source from an output stage connected to a load. The power switch, the first inductor, and the first capacitor are arranged at the input stage, and the second capacitor and the rectifying switch are arranged at the output stage. The ripple-filtering inductor, which may be arranged at the input or output stage, and the first inductor divide the power supplied from the power source, thus the voltage drop of the first inductor is reduced for smoothing the ripple voltage at the output stage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Step-up/down direct current converter","description":"A step-up/down DC converter applied to achieve a characteristic of zero-ripple voltage, which ripple voltage is near zero, is disclosed.
