Modular Multilevel Converters
Expert discussions of cutting-edge methods used in MMC control, protection, and fault detection
In Modular Multilevel Converters: Control, Fault Detection, and Protection, a team of distinguished researchers delivers a comprehensive discussion of fault detection, protection, and tolerant control of modular multilevel converters (MMCs) under internal and external faults. Beginning with a description of the configuration of MMCs, their operation principles, modulation schemes, mathematical models, and component design, the authors go on to explore output control, fault detection, capacitor monitoring, and other topics of central importance in the field.
The book offers summaries of centralized capacitor voltage-balancing control methods and presents several capacitor monitoring methods, like the direct and sorting-based techniques. It also describes full-bridge and half-bridge submodule-based hybrid MMC protection methods and alternative fault blocking SM-based MMCs.
Readers will also find:
A thorough introduction to modular multilevel converters, including circuits, operation principles, modulation, mathematical models, components, and design constraints
In-depth discussions of the control of modular multilevel converters, including output control, centralized capacitor voltage control, and individual capacitor voltage control
Comprehensive explorations of fault detection of MMCs under IGBT faults, including short-circuit and open-circuit faults, as well as fault-tolerant control of MMCs
Fulsome treatments of the control

Helps repair skin barrier
Style: Updated Formula
This stuff is amazing! It has drastically helped repair my skin barrier. I had a flare up of dermatitis right before an important event and this helped clear it!

Like it but expensive
Style: Updated Formula
I like it. It does what it says. I just don’t like the price.

returned- for now
Style: Updated Formula
I was using the lotion version of this for about a year, then went to the balm for more hydration. However, it seems to be breaking me out. I think because it's spring, im not needing as much occlusion as i did during winter. I'm gonna go back to the lotion formula, then pick this up again next winter.
It is a little hard to spread, but I spray the avene mineral water on, let it dry slightly, and press the balm into my skin when its still wet. That helps thin the balm just enough to rub in. Otherwise, it can actually feel kind of rough!

Impressive
Style: Updated Formula
Nice thick cream! I even saw results (skin improvement) within days. I like this way better than their Cicalfate+, as it’s easier to rub in, less greasy, and doesn’t have the water vs cream separation issue. I’m not a huge fan of the pump top for this one, but at least it’s a tube instead of a solid canister (where you can’t see how much is left or get to the last bit).
