Direct State of Health Measurement for Power Devices (DiSoHM)

功率器件直接健康状态测量（DiSoHM）是一个汇集学术界和工业界的项目，其目标是开发一种能够检测和量化功率电子模块健康状况的现场健康监测设备。DiSoHM将大大提高嵌入在恶劣环境中的电力电子系统的可用性，例如离岸设施和海底设备。在这种具有挑战性的环境中使用的电子应用由于其偏远且难以访问的位置而导致极高的维护成本。本项目将开发的技术将有助于通过提供故障预测能力来降低故障维护的成本，故障预测能力可用于安排有效的预防性维护。预计这项技术将在其他高可用性很重要的领域得到应用，如高压直流输电、高速电动火车和航空航天。

Direct State of Health Measurement for Power Devices (DiSoHM) is a project which brings together academia and industry with the objective of developing an in-situ health monitoring device that is able to detect and quantify the health of a power electronics module. DiSoHM wil dramatically increase the availability of power electronics systems embedded in harsh environments such as off-shore facilities and sub-sea equipment. Electronics application used in such challenging envrionments incur extremely high maintenance costs due to their remote and difficult to access locations. A technology such as that which will be developed in this project will help to reduce the cost of breakdown maintenance by providing a failure prediction capability which can be used to schedule effective preventative maintenance. It is expected that this technology will find applicatinos in other areas where high availability is important, such as HVDC transmission, high-speed electric trains and aerospace.
