Hi, I am designing a Line interactive ups transformer and am facing some problem w.r.t. the calculations required for designing. The specs for the transformer are as follows: Primary 1 : 225VAC @1A Primary 2 : center tapped 24-0-24 for push pull inverter @15A Secondary : 225VAC @ 1A Aux : 28VAC @5A (...)
That amount of energy implyes in a non elementar design. I developed a 3KVA ups and a lot of parameters must be monitored ( IacIN / IacOUT / Ibat / VacIN / VacOUT ). +++
Hi, I want to design a small modified sine wave transformerless ups (400 Watt) .Can anyone help me with the block diagram and schematic?? Will be extremely thankful .
Hi Sine wave ups is made with even PIC16F72. But nowadays I see Sine wave ups made with dsPIC. What is the main advantage? Thanks
first of all purchase transformer from ups transformer is moxt expensive than all other things like control board and transistors or fets. You should assembel your ups with 24volts.(because with 12volt it is difficult for beginers and difficult to control much hevy wire almost 25mm square ) And you need two batteries. If (...)
Hi, I have a Taiwan made Generic Line Interactive ups 1000VA. While changing battery, accidentally the negative cord of the battery touched the metal body. As a result, two transistor (C1815) just burnt out. On the other side of PCB, a tiny 3 leg black color parts ( May be a transistor, I don't know what it is) and one 2 leg mini register like par
Any body can provide the total calculation on transformer design with PWM in push pull topology used in inverter circuit. Example- input 12vdc output--220vac VA rating--500va freq. 50hz How the transformer size reduces in inverter & ups with E-I iron core. When i calculate with conventional formula of (...)
I build 1 inverter use 2 MOSFETs ,input 48V ,but output AC only 15VAC,how to increase output ?.I increase PWM but appear DC in output??? Please help me,thank very much!
Hi all, How does work the ups topology that uses the same transformer to INVERTER / BATTERY_CHARGER ? Doesn't it have danger to fire the inverter when public energy return ? regards
