My first thoughts are that the coil is poorly constructed, the primary (blue) winding is covering about half the length, if you are expecting say 40KV corona, the insulation will have to be good to about 20KV. I would try a two or three layer primary with a little more space between it and the secondary winding to prevent flashover. However, your
Hello Techies, While running the brshless dc motor using a vector control software, How to check the High side and Low side Power Mosfet legs on scope? Can they only be shown using some graphical programming like in GUI's or If there is a way to check without softwares(i.e., in CRO) how to see the PWM's of three phases i.e., by inverter switches
Our team has developed a several controller boards for our current Projects for over three years. With little modifications we have used this board in several projects so far. Its structure is as follows: 151355 As you see almost all peripherals are connected to FPGA and The data bus between FPGA and CPU is a parallel
The schematic in post #1 makes no sense. Where's the power supply connected? Also I am trying to get a logical 'OR' signal as a result. What's logical OR for you? Do you mean interrupting either light barrier should give a high output level? In this case, the photo transistors must be series connected but without the LED supply
1) Why the comparison below does not take time complexity into consideration ? 2) How to derive the area and power complexity for "Point-to-Point" , "Simple Bus" and "Segmented Bus" ? 3) Why is "Simple Bus" having larger area complexity compared to "Point-to-Point" ? 4) Why three of them having power complexity of O(n*sqrt(n)) ? h
Single phase synchronous motors usually have low starting torque. It might be that the motor isn't suited for your application. Motors with run capacitor (two windings and three or four terminals) have higher torque and direction can be controlled. I have never seen a ball valve driven by a single phase motor with arbitrary run direction.
Hi All I am current working on a circuit design which involves interfacing an O2 gas sensor I tried to reverse engineer the development board from manufacturer (They don?t supply the schematics) And I believe the circuit that has been used looks something like as shown in the picture below: 151175 It is a three
Thanks, Mr. Brad. Which software would be easy to simulate such problems i.e. three phase circuits?
Assuming you have some money allocated to the task, I would suggest a simple SMS system using a cell network SIM adapter along with a temperature sensor and a simple circuit to monitor the transformer input and output voltages. I suggest monitoring both voltages as it will help to isolate a fault as being before or inside the transformer. You wil
"You do realize that 2 pf is a HUGE amount of capacitance at 2.4 GHz, right?" Obviously not big enough to stop a 2.4Ghz FlySky FS-HF030 RC transmitter. See video below. I do mention in the same post that I have tried a pair of BAT62 diodes that are advertised, in the datasheet, as "Low barrier diode for detectors up to GHz f
The algorithm is described here - Thyristor three-Phase Rectifier In addition, there is also a power factor correction rectifier circuit called a "Vienna rectifier".
Hi, I am trying to figure out if a micro-tel 1200 wide range receiver needs service or not receiver seems to work ok but: If I connect a ham radio receiver at it's 30MHz IF output, I can notice the demodulated AM signals but there is lots of hum also there, so
How do I display the 3-D conformal mesh of tetrahedrals in HFSS? I wasn't able to find the command to do this. Or maybe HFSS doesn't allow you to see the mesh? This is for a patch antenna, or a simple dipole. Also, why doesn't HFSS put "dBi" instead of just "dB"? It's clear they specifically mean dBi (decibels over an ideal isotropic r
Setup: Patch array antenna fed with a signal F(t)=F1(t)+F2(t)+F3(t), in other words there are simultaneously three frequencies. F2(t) signal component may be fed to each patch with arbitrary phase shift. Question: Is it possible to cancel out F2 frequency by feeding each odd-numbered patch with F2 signal shifted by 180? Each odd-element wil
Promach....three questions: * Supply voltage only 1volt DC? Why so low? * Input signal is a current I1. Why not a voltage? * What is the purpose of the output current source I2?
This ".machine ~ .endmachine" describes a sequential block which has four states, two inputs and three outputs. BTW, state transition diagram in the following does not match to netlist description.
We use multiple snap settings. (1) Device Layout (2) Primitive Cell Block Layout (3) Functional Cell Block Layout (4) Cell Place and Route Optimal snap is different for these. Usually I use three different snap settings. Set snap setting any value you like. Post question after learning very basic thin
one strip will need 12V and 6A. 2A per color channel if I understand right. So you'll drive three MOSFET transistors, each capable of switching 12V/2A, to your Arduino and control the LED brightness by PWM.
Hello, i want to ask if there is anybody with some experience in PCB desing with single and three phase active front end rectifiers? I need to simulate voltage and current versions of single and three phase schematics and i kinda need help.
O.K., I see. I don't think there are so many 3 phase IGBT drivers with built-in soft shut down, e.g. not the devices linked in post #2. Manufacturers provide parametric search for features, according to it IRF/Infineon has no three phase driver with soft shut down. What's against FAN73893?
