In an exemplary design, a front-end converter includes a boost circuit having first and second inputs, positive, negative, and neutral output nodes, an inductor, AC inputs, a battery, and first and second devices. The boost circuit is configured to provide a positive capacitor voltage between the positive and neutral nodes and to provide a negative capacitor voltage between the negative and neutral nodes. The first device selectively couples the inductor to a first AC input or a positive port of the battery and the second device selectively couples a negative port of the battery to the second input. The inductor is coupled to the first input and is shared between an online mode of the converter and an on-battery mode of the converter. The battery is coupled through the inductor to the first input during the on-battery mode."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"AC-to-DC conversion","description":"A front-end converter in an uninterruptible power supply system is described.
