Design of a SiC-based modular multilevel converter for medium voltage DC distriution system
2017 IEEE Applied Power Electronics Conference and Exposition (APEC), 2017Co-Authors: Jianghui Yu, Rolando Burgos, Niloofar Rashidi Mehrabadi, Dushan BoroyevichAbstract:The Modular Multilevel Converter (MMC) is a promising converter choice for Medium Voltage DC (MVDC) distribution systems, where SiC devices can be readily adopted taking full advantage of this semiconductor's properties. Specifically, 1.7 kV SiC MOSFETs are used to build 1kV modules operating at 100 kHz, thus eliminating the need to use multiple modules to generate a high equivalent switching frequency. Furthermore, a full-bridge configuration is used to take advantage of the additional control and energy storage capabilities that it offers when compared to conventional half-bridge modules. The full in-depth Design, Controls, and testing of the MMC prototype for MVDC distribution systems is presented in this paper, including among others: component selection, control algorithms, control hardware implementation, precharge and discharge circuits, and protection scheme. Experimental results are presented to demonstrate the proposed SiC-based converter.

Development and use of analytical quality specifications in the in vitro diagnostics medical device industry
Scandinavian Journal of Clinical and Laboratory Investigation, 1999Co-Authors: Donald M. Powers, N GreenbergAbstract:Manufacturers of in vitro diagnostic (IVD) medical devices have become integral partners with their customers in determining the quality of laboratory results. Design Controls imposed by ISO 9001 quality system standards and various regulations require manufacturers to implement a formal Design process, which begins and ends with customer requirements; For IVD systems, this means that manufacturers must establish analytical quality specifications as part of their Design input. This provides greater assurance that commercial products will satisfy customer requirements. In the case of quantitative IVD measurement systems, analytical quality specifications include total allowable uncertainty (bias, imprecision, non-specificity). The primary source of customer requirements is the laboratory-customer, who should have established analytical quality specifications based on the needs of its physician-clients. The total allowable uncertainty budget is allocated in the Design process to the individual components of the system, such as reagents, instrumentation, calibrators and accessories, and to other factors such as operator, specimen and environmental interactions. Their performance must collectively meet the total allowable uncertainty specification when they are finally integrated into a measurement system. The Design control model requires objective evidence that Design specifications have been met (verification) and, finally, that the system will satisfy the needs of its intended users (validation). Compliance with the quality system standards is monitored through independent audits, government inspections and post-market surveillance.
