I was looking at the IEEE guideline and noticed they specifically state that DC and AC are not capitalized. I've seen both and capital looks better to me so I'll probably stick with that. I haven't seen subscripts addressed so I was wondering if there was any specific notation. Since there's...

When specifying DC vs AC voltage excitation, is it appropriate to type 50 VDC with DC as a subscript? OR should it be "V DC"? The same concept if it were AC.

These are interesting. I've never heard of these, so thanks for sharing. This looks like something I may be able to use. I'd be interested in seeing what the current looks like with DC current, but it looked ok up to 10 kHz.

I'll check into the LEM. 10 mA is higher than I wanted, but it's one of the higher sensitivities I've seen. I don't necessarily need isolation, I'm interested in this over a CVR since I don't have to break the circuit.

I have been looking for sensors to detect DC current in the microamp range. I've been looking into hall sensors. I found an IEEE papers talking about one they designed, so I'm not too sure they're commercially available in that low of a current range. I haven't found any on DigiKey anyway. I...

Sorry, I didn't realize there was confusion on what full bridge was referring to. It is referring to totem pole MOSFETS...or any other active semiconductor switches I suppose. My understanding of what's meant by fault current is the same. By fault tolerance, I THINK they're referring to...

Thats the way that its worded in all of the papers that I've read regarding the MMCs that mention the benefit of the full bridges fault tolerance. So it seems like the community reading it understand what's meant and we do not. Thanks for trying to help. Now I don't feel like I'm missing...

Maybe you can help me with a simpler more elegant way to explain how it protects from the dc fault current of the converter? I posted the full paragraph and cited the paper I got it from, but ill post part of that except below again. This is referring full bridge submodules in a MMC. "the...

For clarification, SM is submodule and MMC is modular multilevel converter.

I'm not referring to just redundancy. Here is a quote directly from the paper " A Comparison of the Battery Fault Tolerance of Modular Multilevel Converters with Half-Bridge and Full-Bridge Submodules" "Since the half-bridge SM has fewer components and lower power losses, it is more commonly...

I think it has more to do with it offering protection for the load. In the event of a fault, you can circulate the high current through the bridge to save the load. Thats about as far as my understanding goes, which is why I need to learn more. But it is possible as you mentioned because you can...

I think this part was added after I replied. I'm not sure if those are fault tolerant as well because that's actually part of my question. I guess it is not clear though so I apologize. What is fault tolerance and how is a full bridge when a half bridge is not? I would assume there are...

One example is this paper..."Open-Circuit Fault Diagnosis and Fault-Tolerant Strategies for Full-Bridge DC-DC Converters". Another is this one..."Implementation of a Fault-Tolerant AC/DC Converter for Permanent Magnet Synchronous Motor Drive Systems" which can be read here...

Why is it said that full-bridges are fault tolerant compared to half-bridge?

My specific system will benefit from having the MOSFET base plate floating. Are there any downsides to leaving a MOSFET base plate floating? Are there any reasons not to?
