Nothing preventing me, but if I can avoid re-inventing the wheel that would be good. Would be good to hear about others that implemented such systems. That is, a custom made setup, not a comertial device.
Latelly I've been pondering on the best way to make myself a solar battery sort of setup.
What I have:
-> 1-4 250Watts Panels, 60 Cells
-> 2KW Li-Ion battery, to be set as 12-96V
Ideally I would like to have a setup similar to a transfer switch, where the power I was able to generate from the...
I'm creating a circuit to drive a MOT with variable output to a magnetron.
Please no nonsense high danger power supplies and the like. I'm aware of all this.
I haven't seem to find much on magnetron power supply hacking. Has anyone seen projects on such?
I've did a couple of simulations and...
Correct, which is the nominal power rating, since the devices are 115VAC to start with. This is how I'm currently implementing it, but has the issue observed with EMI, hence I'm pondering other solutions such as PWM/or cycle skipping.
I've been reading a bit on trailing edge dimming as well...
Since I often travel between Europe and America I have a number of work appliances that are AC 110V, fed here in Europe using a high power phase dimmer. These are resistive or have small universal motors.
I'm happy functionality wise (in fact I can even regulate power as a bonus), but I was...
Thank you, will do so.
I'm not too worried with the SCR switching at 100Hz, the concern I was asking was if I were to replace the SCR with a switching regulator of some sort as a pre regulator before the linear stage (just pondering options).
When you say SRC's are you suggesting me to use...
Yes, I will use a choke rated for the current I need at the output to smooth things out. The SCR/TRIAC would be placed on the secondary arranged in a way that the freewheeling currents from the choke do not interfere with its operation.
Thank you for your thoughts. I will, on due course, make...
That works pretty well in saturation for a switching regulator, my concern is that as an analog amplifier working on the linear region, for the same gate voltages one device may inherently conduct more current than the other - the characteristics while operating on such region are not so well...
Hi guys,
I have a question. I dont normally see IGBT's or mosfets being used in linear power supplies. Many of the components on these are only rated for their output load when TJ = 25C and the transistor quickly burns under short circuit conditions.
For a 0-30V 5A (or 0-60V 2.5A) power supply...
Hi all,
I'm trying to simulate a boost converter for a constant current led driver, power factor corrected.
The AC source is nominal 12VAC, 17V Peak, 50Hz frequency.
Of interest is frequency of oscilation and input/output current waveform.
I dont know how to set the graph to show a time...
Fixed as you have 10 leds making the letter A and you only need to supply power or matrix in wish you have row and collumn and you power the necessary leds to make whatever letter you want, such as in a display.
Assuming the first (you power a fixed letter each time) then a 555 clocking a 4017...
Not so simple... Duty cycle would be 0.02, which makes regulation nearly impossible to achieve. A buck withp ulse skipping might do, but the inductor would have to be physically large. Easier to use a buck converter to step down Input voltage to 300VDC. Altough if the power was low a linear...
Are the letters fixed or are you using a graphic matrix? If the first and you just wish to change the current letter to other, yes a 555 coupled with a 4017 could certainly be used.
This will run from wathever supply you want. How much current is the issue. For 10 leds 10-20mA per led is...
I Think even if they travelled further it would be neglegible. There was a debate a few years ago about yellow versus white for the front fogs, but eventually white has won, since in reality the yellow light was an ordinary bulb with a filter... which in practice ends up reducing the total...
