摘要

Sundstrand正在积极研究270-VDC，混合115-VAC系统所需的技术，以满足在提供大部分负阻抗负载时的电能质量和稳定性要求。该技术演示系统的设计重点是组装一个高度灵活的测试系统，该测试系统能够为成功设计和构建高效、高可靠性、容错、低重量、低成本的混合动力飞机电气系统提供必要的数据和经验，以供未来应用。迄今为止的数据表明，航空航天标准AS1831或MIL-STD-MS704E的电压调节要求可以用最先进的技术来满足。结果表明，当源负载阻抗匹配不当时，系统会出现不稳定。源阻抗和负载阻抗的测量结果在量级和相位上都与分析预测结果相当吻合。

270-VDC/hybrid 115-VAC electric power generating system technology demonstrator

Sundstrand is actively investigating the technologies required by 270-VDC, hybrid 115-VAC systems to meet power quality and stability requirements when supplying largely negative impedance loads. The design of the technology demonstrator system has focused on assembling a highly flexible test system that is capable of providing the data and experience necessary to successfully design and build a high-efficiency, high-reliability, fault-tolerant, low-weight, low-cost hybrid aircraft electrical system for future applications. Data taken to date indicate that voltage regulation requirements of Aerospace Standard AS1831 or MIL-STD-MS704E can be met with state-of-the-art technology. It is demonstrated that with improper source/load impedance matching, system instability can occur. Measurements of source and load impedance compare reasonably well in both magnitude and phase with analytical predictions.<>
