Disinfecting Robots Power Delivery Network Case Study

This case study focuses on the power delivery network (PDN) for disinfecting robots that utilize UV lamps and disinfecting sprays to eliminate pathogens in large, high-traffic areas such as schools and hospitals. The robots require efficient power solutions to operate high-intensity UV lights and pumps, as well as sensors and motors for autonomous functionality. Key objectives include enhancing efficiency to extend runtime, managing high-temperature operations, and supporting various point-of-load voltages. Vicor's high-power density and high-efficiency power modules are highlighted as solutions that optimize design space and support a wide range of loads. The case study details the use of Vicor ZVS buck and buck-boost regulators, which provide lightweight and compact regulation, achieving high efficiency rates exceeding 95%. The design allows for the regulation of battery voltages from 24V to drive various components, showcasing the modular approach to PDNs that significantly reduces space requirements compared to traditional converters.
