 08 Nov 2006 12:10 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 ?

Hi Guys,
Somebody know how to calculate transformer ratio in that topology ?
Note1 : It uses rectified sinusoid to charge battery !!!
Note2 : Either at charge mode and operating mode.
