SBIR Phase I: High Performance Single Inductor Multiple Output DC Converter

该项目更广泛的影响/商业潜力将增强电力电子行业的科学和技术理解，并有可能提高性能、电力效率，并节省空间和成本。 当电子设备的复杂性不断增加且性能需求日益提高时，这种基于控制的解决方案将为电力电子领域提供新的选择。这项技术有许多应用，包括消费电子产品、智能手机、便携式计算机、电信设备、服务器和数据中心、电动汽车、可再生能源系统和国防应用。 该技术与功率水平无关，可应用于芯片（半导体）设备以及高压电网电力系统。对于这些领域，能源消耗、成本和电源电路的物理尺寸是最重要的问题。 即使这些领域的最小减少也受到高度追捧。这个小型企业创新研究 (SBIR) 第一阶段项目旨在通过消除由多个转换器组成的电源架构并用高性能多输出转换器（可以完成 2-4 个单独转换器的工作的转换器）取代它们来提高效率、节省空间并降低电源电路的总体成本。 目前，电子设备中的电源架构使用多个单独的转换器，有时多达 60-100 个，具体取决于应用。 多输出转换器的其他尝试都是极其复杂且性能低下的设计。 该方法通过创建一种新的功率控制方法来关注功率转换的数学基础，该方法可以同时控制每个电压输出，同时还提供高稳定性和性能。这项研究预计将生产出一种 3 输出数控降压转换器，该转换器使用单个电感器，具有更好的电效率，需要更少的空间，并且成本低于 3 个单独的转换器。

The broader impact/commercial potential of this project will enhance scientific and technological understanding in the power electronics industry and has the potential to improve performance, electrical efficiency, and provide space and cost savings. This control-based solution will provide a new option for the power electronics community at a time when electronic devices are increasing in complexity and experiencing greater performance demands. There are numerous applications for this technology, including consumer electronics, smartphones, portable computers, telecommunications equipment, servers and data centers, electric vehicles, renewable energy systems, and defense applications. The technology is power level agnostic, and can be applied to chip (semiconductor) devices as well as high voltage grid power systems. For these sectors, energy consumption, cost and the physical size of the power circuitry are of paramount concern. Even the smallest reduction in these areas is highly sought after.This Small Business Innovation Research (SBIR) Phase I project seeks to improve efficiency, save space, and lower the overall cost of power circuitry by eliminating power architectures composed of multiple converters and replacing them with high performance multiple-output converters, converters that can do the job of 2-4 individual converters. Currently, power architectures in electronic equipment use multiple individual converters, sometimes as many as 60-100 depending on the application. Other attempts at multiple-output converters have been extremely complicated designs with low performance. This approach focuses on the mathematical fundamentals of power conversion by creating a new power control methodology that simultaneously controls each voltage output, while also providing high stability and performance. This research is expected to produce a 3 output digitally controlled buck converter that uses a single inductor and has better electrical efficiency, requires less space, and costs less than 3 separate converters.
