I am making mini ups circuit as a project and in the project there is a part with variable resistor of 10k and transistor BC548. what I don't understand is that in the description it says that variable resistor and transistor acts as voltage comparator. i really don't know what that means. plz help me out!!

i was given this project in school. i just need the circuit daigram
Hi how are you every one hop all is fit n fine there dear friend's i have one inverter iam looking that very small and simple circuit ideside we make copy for this then i make whol schematic and make pcb board ...know i am go to electronic's parts shop and get the ic seam number and incert the ic in base ...... nathing eles ..mean no
I am Currently having Digilink DGU 600ML ups,i.e 600VA,The ups has no load protection. I need to run only my DSL Wifi router which consumes 12V 1A=12watts. How can I run the device for long hrs..Coz the ups has no load protection and it goes off after minutes time.How do i make the modification Have attached the ups (...)
Hello I need a SINE WAVE ups DESIGN ....SCHEMATIC , PCB DESIGN ........, and should be based on MicroController PIC any ! I'll pay for that ......i need this design and all the system with in 45 days ! If any one can do me for the further details ! Thanks Best Regards Hasan Farooq
In my opinion use a single ups . If you use 8 ups it lost lot of current as losses .and a lot of places. Calculate the full Load with the help of an electrical experts and take decision.
i shell be want to find out sine wave ups circuit with pcb plz if you have plz gave me a complete things about sine wave haroon pakistan
Pls ref some ups circuit or other inverter circuit.this forum can find inverter circuit.
The "N" part is significantly slower and has higher capacitance than the "NF" part. That difference may or may not cause trouble in your ups circuit. Did you replace the MOSFET because it was damaged? Maybe the circuit has another malfunction that killed the MOSFET.
hi , any body help me to get amra raja make battery charger and ups circuit diagram thks
FROM: HEATSINK PLATEN: The required 1cm./5W will make it neccessary to use an Al. plate 5.5" X 6" X .125"Th. using the IRF44's (good choice too). Isolate them 1. I would avoid the LC and go with a 60Hz source MM5369. I noticed the 220VAC so you are using 50Hz European. The Xtal can be tweaked to tha
You have to describe your situation and application in detail. Is it the DC pulse or impulse. Level of the DC? pulse width? The basics would be to turn on a npn transistor and use this transistor to turn on POWER MOSFETS, if you need more power add multiple mosfetets in parallel. you can see a simple ups circuit to see the mosfet configuratio
Most of the ups circuit I have seen ,has four relays and transformer with three coils on primary side. How they drive the battery charge using these relays ? 107215 107216

I have an Old ups and I want to connect it to my computer with a DB9 cable or another like it but the manufacturer of the ups is Japanese and I cant understand that language , anybody have an SENDON ups (1000 VA) or Know the pinouts of the connector (db9 to serial) :?:
Hi All, I need service/user manual for IMV victron ups D3-11. Can anyone help me? Thanks and Regards Balaji
thank you for ur reply. But, actually, I don't mean ups. Just an AC to DC convert mains voltage to about 24VDC to power a circuit, say some MCU application circuit. And problem is the line to mains will be cut for a while, say up to 1 sec. So, how can I keep the DC voltage alive while AC loss? I know using CAPs will do. I try to find some (...)
Yeah; I certainly agree with your point there. My point is only that most people on this forum are likely to be grown-ups, if they decided against working through the question - it is their own choice. I also feel that people have been very trigger happy with the homework assumption. Particularly, the question in this thread does not strike me as a
This circuit works as a comparator. Consider the branch with Vinp. If Vinp increases, then the current through the PMOS differential pair at that end decreases. Hence, the Vds drop on its active NMOS load decreases. For a moment consider that load to be a resistor because of the rds being modeled as a resistor. When the current is decreasing, then,
Hi Where to find DSP - Based Pure sinewave ups Inverter circuit schematic. url required, Thanks Ranjan Nandi
ups is not constructed in a way to handle long time load . Transformators are not choosen to work in continuos mode operation. Then switching MOsFET's hs to be put onto radiators. better will be increase number of MOSFET's connected in parallel if ups is t work longer than expected. Then it comes to charge current you have to adjust to get batt
