## UPS Transformer Design and calculation

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 (...)

## 50 Hz to 60 Hz generator

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 ). +++

## design of transformer- less ups (modified sine wave)

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 .

## Sinewave UPS in dsPIC

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

## UPS designing. where to start?

Hi, I have decided to design a ups for my home. I am aiming for 2kVA ups. Now the thing is where should I start. Is there any book for ups out there. I have made quite a search on the internet but most of the data I found was either out-dated or incomprehensible. For example the inverter circuit I found was of 1998 (

## How to correct output voltage of a UPS?

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

## transformer design help

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 (...)

## how to increase amplitude output of inverter ups?

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!

## UPS - How to use same Transformer to INVERTER/CHARGER

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

## Which simulating software is better to select?

To 3D simulate and design inductors in ups and 3 phase transformer. Which simulating software is better to select? Tx.
