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

该项目更广泛的影响/商业潜力将增进电力电子行业的科学和技术理解，并有可能提高性能、电气效率，并提供空间和成本节约。这种基于控制的解决方案将为电力电子界提供一种新的选择，因为目前电子设备的复杂性越来越高，性能要求也越来越高。这项技术有许多应用，包括消费电子、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。对于这些部门来说，能源消耗、成本和电力线路的物理尺寸是最重要的问题。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，代之以高性能多输出转换器，从而提高效率、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，根据应用的不同，有时多达60-100个。多输出转换器的其他尝试都是性能极低的极其复杂的设计。这种方法通过创建一种新的功率控制方法，同时控制每个电压输出，同时提供高稳定性和高性能，专注于功率转换的数学基础。这项研究有望生产出一种3输出数字控制降压转换器，它使用一个电感，具有更好的电气效率，需要更少的空间，并且成本不到3个独立的转换器。

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.
