Two-Phase MMC Based on Modular Multilevel Series/Parallel Converter for Back to Back Power Systems

The MMC converter is the key topology for HVDC applications. In these systems, a major complexity is the number of modules and components required per phase to achieve nominal voltage and current levels for applications in transmission system. In this paper, the topology and control of a two-phase MMC system for HVDC applications is presented....

A rugged FBG-based pressure sensor for water level monitoring in dikes

This paper describes the implementation of an FBG sensor to measure water levels in a dike. The sensor is based on a 3D-printed mechanical transducer through which the external pressure is converted into longitudinal strain exerted on the fiber. An additional FBG integrated within the sensor measures temperature and is used to compensate for...
