SBIR Phase I: CMOS-Integration of Isolated AC/DC conversion with Integrated Powerline Communication

这个项目更广泛的影响/商业潜力是，它将彻底改变几乎所有现有和未来的住宅和商业电子设备中存在的交流-直流转换器。降低转换器的复杂性和提高功率效率将为这些设备的制造商和最终消费者极大地节省成本，使其能够被社会各个角落所采用。这种截然不同的集成转换器还将为这些电子设备带来电力线通信，这将改变游戏规则，使电子开发人员能够在众多市场中为其产品添加智能，例如家庭和办公室物联网设备，交流供电中瓦数（~5W）电子产品，以太网供电和智能LED照明。这个小企业创新研究（SBIR）第一阶段项目将创建一种替代的集成AC-DC转换器架构。现有的转换器有许多笨重、昂贵且不可靠的离散磁性元件，将被这种基于集成电路（IC）的解决方案所取代。该项目的结果将是减少占地面积，减少BOM计数，高效转换器为中等瓦数（~5W）的电子负载。该项目还将以更小的占地面积和更低的BOM计数支持低瓦数负载（1W），展示了该技术的可扩展性，这是现有反式交流-直流转换器解决方案无法选择的。第一阶段基于ic的转换器性能的验证将为第二阶段提供基础，并纳入电力线通信。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The broader impact/commercial potential of this project is that it will revolutionize AC-DC convertors that are present in nearly all existing and future residential and commercial electronic devices. Reduced convertor complexity and increased power efficiency will result in extreme cost savings for both the manufacturers of these devices as well as the end consumers, enabling adoption to all corners of society. This dramatically different integrated convertor will also bring powerline communications into these electronic devices, a game changer that will enable electronics developers to add intelligence to their products across numerous markets such as home and office IoT devices, AC powered medium-wattage (~5W) electronics, power-over-ethernet, and smart LED lighting.This Small Business Innovation Research (SBIR) Phase I project will create an alternative integrated AC-DC converter architecture. Existing converters have numerous bulky, expensive, and unreliable discrete magnetic components that will be replaced with this integrated circuit (IC) based solution. The result of this project will be a reduced footprint, reduced BOM count, efficient converter for medium wattage (~5W) electronic loads. This project will additionally support low wattage loads (1W) with an even smaller footprint and even lower BOM count, showcasing the scalability of this technology which is not an option with existing fly-back AC-DC convertor solutions. Validation of the Phase I IC-based converter performance will provide a foundation for Phase II, and incorporation into powerline communications.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
