Hi,
VFD's are used to change the speed of Induction motors, which can be modelled as an inductor.
Depending on the inverter topology (Voltage Source / Current Source) corresponding variable is changed.
However, both Voltage and current frequencies will be same.
The current/voltage/Torque...
How about Parallel / Rs232 interface if our data rate is ~ 1MBps ?
Also keep in mind that 480Mbps for USB is in bust mode. Not consistent.
Ease of implementation depends on your knowledge and skills.
You may get some IP cores / built in blocks for FPGA implementation.
As mrflibble commented, its...
Hi Charles,
It was an interesting topic.
Hope the following link on may be useful for you. https://www.ni.com/white-paper/14044/en/
I do not have any experience, but as an engineer, I think you need to get a specific product.
In this link, the author was looking for something like your's...
Hi Ravi,
They do not charge for any import duty for small quantity items.
I have recently ordered items from Digikey and Mouser to a relative coming to INDIA (To avoid 40$).
A small amount is taken as TAX (~ 6$ for 100$ bill).
Try to get from any Indian distributors if possible.
You can also...
Hi,
Plz see this discussion: https://forum.arduino.cc/index.php?topic=142929.0
FPU is used for calculation, where high calculation accuracies are must.
So if you have to do an operation like 4.5679 * 3.2289, How will you implement it?
Here is where IEEE 754 standard for Floating point...
Hi Godup,
I could not understand your requirements correctly.
FPGA is a digital device.
In addition to CMOS inputs, it has the ability to receive LVDS signals, which are also Digital.
If you just want to coursely segregate the signal (compare), you can trick the system by providing...
Hi marinet,
Here the issue is that Matlab to HDL conversion is not easy ( mainly for synthesis ).
The division in your algorithm is a major problem. Division algorithms are in fact not straightforward to implement in digital design.
Basically you will not get division result in one clock...
Hi Hiten,
Your board seems to be Altera DE-2 board.
It uses Philips ISP1362 USB controller.
I think you can get the sample programs for NEOS programming from altera website.
See https://www.altera.com/education/univ/materials/boards/de2/unv-de2-board.html
DO you have a USB port in your board?
If not, you will have to buy a UBS module, which handles USB transactions and gives data through SPI/I2C protocols.
In my opinion, do not go with implementing USB protocol unless it is 1-2 year project.
Just go through this link **broken link removed**
Can you Please be more specific? Are you intending to implement USB-Physical layer or just data transfering through some existing interface?
You can go through https://www.usb.org/developers/docs for understanding the USB specification.
If you want data tranfer, it depends on what is implemented...
Hi,
I am not against Analog meters. But IMO if you retrofit an analog meter with digital circuits to make it 'smart', all the problems of both analog & digital will manifest with additional problems due to interface (eg: spring forces may change, affecting the accuracy). Anyway if you want...
Hi Disha,
Digital meters can be designed with far better precesion and accuracy compared to analog.
Problems with analog meter is not only with accuracy.
They have very delicate mechanisms and are very prone to errors.
Also if you try to retrofit a mechanism to convert to digital, its double...
I would like to share my experience with you.
I was an FPGA design engineer with some experience of board design. Recently I have taken up a slightly complex 'hobby' project for one of my research project which includes board design. My intention was to understand the full design flow...
Hi Disha,
In my opinion, that approach is not right. It will have deficiency of both Analog & Digital.
1. You can implement using micro controller boards. Make it powerfull by writing code to derive more parameters (eg: pf) and transmit information.
2. You can go further by making...
