Thanks for the comments. In my opinion multilevel inverter would have less chip area because the switching losses are smaller (and often conduction loss too), and main factor for chip area is the losses and heat.
Blocking voltage is more about drift region thickness, I was wondering how I can...
Hi,
I need to compare silicone area needed for conventional 2-level inverter and a 3-level inverter. My first question is how can I make 1200V silicone die comparable to 600V type regarding to silicone area comparison? factor of 2 (even though I think this approach is wrong)?
My second question...
Hi,
I was wondering what standard(s) should be followed for power electronic devices' insulations? The test procedure, PI, DAR values... . I know for the rotary instrument it is IEEE 43. I could not any thing with search, so I would be grateful if you share any related standards for low voltage...
If I am wrong please correct me; If saturated value of B is same for all cores. But I think it is deferent. For example, Amorphous cores go to the saturation with smaller H value, but with same core size saturated B value is almost 10 times of N87,... .
I need material with quite opposite...
Hi everyone,
I am looking for a magnetic material preferably available in ring shape with smallest B-H curve. I mean it goes to saturation with very small A/m value and also it has low saturation B.
Smaller than N87. smaller better.
Thank you
Thank you for your response.
Actually, GND_system and GND_internal are different, Because there is a MOSFET (reverse polarity protection) between them. That makes sense. But why have they separated GND_internal and GND_shifted? below 12v they are tied together; between 12 up to 30, they are...
Hi,
I was looking into the schematic of one of Infineon's demonstration boards which can be found on the link below:

There are 3 ground levels...
It is water-cooled. We also have limitation in flow and allowable outlet water temperature (42C). Total loss in the switch is 3960W I am tring to design to design for junction temperature 120-130C, in that case, case temp will be 52C. I am delving into datasheet and trying to come with...
Actually, it is not normal operation mode. For normal operation I usually I choose conservatively according to constant DC current= max current+20%. For this project Customer asks converter to have capability to supply twice nominal current for 2 seconds, in case there is a fault in the grid. I...
The problem is that the modulation is space vector modulation and the duty ratio varies through one cycle. Seems this curve is drawn for 50% duty cycle. Am i right? what's the cool off time (OFF time of the IGBT after one pulse)
Thank you all for the information. I am not hiding; actually, I am looking for couple of components from ABB, Fuji and Infineon. I just shared a picture because it is easy for reader to look at rather than going through datasheet. The module I shared part of datasheet is Infineon FZ3600R12HP4. I...
Hi All,
I am dealing with designing a converter circuit. Before I chose IGBT with continuous current even more than nominal output current, but now pricing is critical and I need to keep it low. My question is about Repetitive peak collector current? what this current means? 1ms! Does not it...
We have lots of power quality issues related to grid voltage like fluctuation, sag, swell, harmonics, etc. In my opinion, a single-phase PLL cannot track Angle correctly in this situation. A simple method to implement PLL through software is using Park transform and Moving Average Filter to...
Hi,
I am working on a grid-connected converter. I need a 3-phase PLL. I prefer not to implement it through software. I would be grateful if you introduce me a 3-phase PLL chip with low noise susceptibility; if it is available and you are aware of. I found a couple of single-phase PLL, but not a...
I searched and I found this. The calculation sounds correct in this paper, so we can calculate by using this paper:
IEEE TRANSACTIONS ON POWER ELECTRONICS, VOL. 28, NO. 6, JUNE 2013
Analysis of the Passive Damping Losses in LCL-Filter-Based Grid Converters
