1. 1. Microstructure and Mechanical Investigation ofCarbides Particles Reinforced High AusteniticManganese Steel

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Abderrahim Ait ouakrim; [2023]
   Keywords : Metal Matrix Composites MMCs ; Manganese steel; Carbides particles; Wear resistance;

   Abstract : The objective of this study was to produce a metal matrix composite (MMC). This compositematerial proves highly suitable for scenarios involving abrasive wear, owing to the exceptionalhardness of carbide particles, in conjunction with the remarkable ductility and capacity for workhardening found in Hadfield steel.

3. 2. IMPROVED SUB SYSYEM ENCLOSURE

   University essay from Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

   Author : EMMANUEL PETER; ALAN SHAJI; [2022]
   Keywords : Prefabricated Enclosure Wall Panel Systems PEWPS ; Modern Methods of Construction MMC ; Panelized systems; Prefabricated panels; Stainless steel 316; Lean; Nonconformities;

   Abstract : Building envelopes are perhaps the most influencing players on assuring indoor comfort conditions, in alliance with their impact on the sustainability and energy-efficiency of the building during operation. However, given the multitude of commercial solutions available on the market and the use of different criteria and inconsistent semantics among the existing categorization/classification systems of construction objects, there is still a need for uniformization of the many regarding the main Prefabricated Enclosure Wall Panel Systems (PEWPS) for building applications.

4. 3. Closed-loop control and data- recording of a modular-multilevel converter (MMC)

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Longgang Su; [2022]
   Keywords : Modular multilevel converters MMCs ; filed programmable gate array FPGA ; direct memory access DMA ; energy closed-loop control; data recording; ethernet.; Modulära multilevel-omvandlare MMC ; filed programmeable gate array FPGA ; direkt minnesåtkomst DMA ; energistyrning med sluten slinga; datainspelning; ethernet.;

   Abstract : Modular multilevel converters (MMCs) are the preferred converter solution in flexible ac transmission systems (FACTS) and high-voltage direct current (HVDC) applications. This is due to the high quality of the voltage and current signals, lower overall losses, and fewer problems with switching-related EMI. READ MORE

5. 4. Battery Balancing on a Full-Bridge Modular Multi-Level Converter

   University essay from Linköpings universitet/Fordonssystem

   Author : Junyu Lin; [2022]
   Keywords : MMC; BMS; Modular Multilevel Converter; SOC; state of charge;

   Abstract : Batteries are becoming popular in the trend of electrification. Performance andlifespan of a battery pack are closely related to how it has been utilized. Withproper balancing control to slow down aging process, variances of capacity andresistance between battery cells can be maintained at a better level. READ MORE

6. 5. Comparative Analysis of Several Designs of Modular Multilevel Converters with Interleaved Half-Bridge Submodules

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Lingyu Chen; [2022]
   Keywords : Modular multilevel converters MMC ; interleaved half-bridge submodule; interleaved converters; power loss calculation; converter efficiency; converter dimensions; Modulära multilevel-omvandlaren; interfolierad halvbrygga submodul; interfolierade omvandlare; effektförlustberäkning; omvandlareffektivitet; omvandlardimensioner;

   Abstract : The Modular Multilevel Converter (MMC) is one of the most commonly used active converters in the high-/medium-voltage sector due to its many advantages such as high scalability, high efficiency, modularity and low harmonic contents. However, in low-voltage and high-current applications, classical MMC designs are not very economical. READ MORE
