Hello.
I want to be able to write a script(or something) that would accept a short text or a number of words as input and then use those words to create a larger text, so that the resulting text depends on what words where given as input.
But I have no idea of any software or language that...
Hello.
I have what I think is a pretty neat idea, the latest laptop I bought feature a USB Type-C port which supports USB Power Delivery(USB PD)(my port is actually a Thunderbolt 3 port but it is compatible with USB 3.1 Gen 2 & USB PD, but let's not get into all that stuff) which means the such...
Hello.
I acquired a sensor called S25P050D15X with the intention to use it in a circuit to measure the saturation current of ferromagnetic cores i.e. inductors and transformers, but my concern is this, the sensors datasheet can be found here.
Further down on page 2(the last page) there is this...
This is for a single-phase motor(fan).
I have been thinking about voltage doubler directly at the mains but I don't know math good enough to be able to actually calculate the current that such a circuit could be made to supply, but from what I have read the current are very low.
I don't...
Hello.
I am building a SPWM Variable Frequency Drive that should be able to output at least 240Vrms @ 50Hz to drive a fan that may consume at most 30W, as far as I know for that I need a DC rail of 450Vdc.
What is the simplest/easiest way to achieve a 450Vdc rail?
My first idea was a PFC...
Hello.
A couple of years ago or something I was getting advice here on EdaBoard about how to design a dual-channel Lock-In Amplifier(LIA) with the goal of being able to measure complex impedance across a frequency range of 10Hz - 1MHz, I was told(I have received the same answers from other...
I didn't think that I would need to dim lower than 150W, so I chose the driver version featuring an internal potentiometer that can be adjusted from the outside, in hindsight I should have chosen the one which featured a input to which one may connect a 0V - 10V signal, a PWM or a potentiometer...
Hello.
I have a high-power LED light armature, the light is dimmable from about 150W to 280W, but the 160W is still to bright.
I am using a constant-current LED power supply from Mean Well(which feature an adjustable output current, hence the dimmable light) and I was thinking of simply using a...
The OPA544 and OPA541 have some desirable features but I think I will go for the OPA564, it has only a +-12V supply capability(the original design uses a OPA544 and +-35V) but it has far higher bandwidth(full power bandwidth of 1,3MHz at gain = +2, OPA541 have a full power bandwidth in the lower...
Hello.
I've found this for me very interesting circuit in a paper on Reaserchgate that shows the schematic for a 2mA - 2A AC/DC constant current source made with two OPA544 high-power op-amps, the first is just a unity-gain buffer to supply the required input current to the second which is part...
Hello.
I have been reading about multi-phase synchronous buck-converters and there benefits compared to a ordinary buck-converter, and I have seen but not really read about multi-phase boost converters.
Multi-phase converter means that instead of having a synchronous buck-converter built with...
Hello.
By now it was quite a while ago but I have been talking about building a high-current mcu controlled vaporizer before, here is a schematic(please note that this is now no longer valid at all, it wasn't ever finished but now it is completely scrapped), all the different coloured dashed...
Re: IR2110 Full-Bridge, heating coil heat distrubution experiment, what about dead-ti
Thanks for all the answers, they have sure given me some food for thoughts.
Just ta clarify, I have never used a H-bridge before and due to what I have been told about the heating of a coil I thought that I...
IR2110 Full-Bridge, heating coil heat distrubution experiment, what about dead-time?
Hello.
I have heard that if a heating coil(it isn't a coil as in inductance coil, it's simply a resistive heating element wound as a coil) is supplied with current in only one direction the heating of the coil...
It has been sitting on the floor of my lab/work room for a while now and I if I actually do what I intend to do today I am about to give it a good cleaning over. I can't stand dirty main cables... But it is rather clean as it is but I think that given how long this will be within my ownership I...
