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.

该项目更广泛的影响/商业潜力将提高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，并节省空间和成本。 这种基于控制的解决方案将为电力电子社区提供一种新的选择，因为电子设备的复杂性越来越高，性能要求也越来越高。该技术有许多应用，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。 该技术与功率电平无关，可应用于芯片（半导体）器件以及高压电网电力系统。对于这些部门，能源消耗，成本和电源电路的物理尺寸是最重要的问题。 这一小型企业创新研究（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（可完成2-4个独立转换器的工作），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，根据应用，有时多达60-100个。 多输出转换器的其它尝试是具有低性能的极其复杂的设计。 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，同时还提供高稳定性和性能，专注于功率转换的数学基础。这项研究预计将产生一个3输出数字控制降压转换器，使用一个单一的电感器，具有更好的电气效率，需要更少的空间，成本低于3个单独的转换器。
