IGBT modules for Online Ups: operating principle of uninterruptible power supplies<\/h3>\n\n\n\n

Online double conversion UPS systems are used for sensitive equipment protection (bank servers, hospital operating rooms, etc.) that require uninterrupted power supply during critical situations (example blackout).<\/p>\n\n\n\n

When occurs a voltage drop at the UPS input, the system is still able to keep the output voltage perfectly stable.<\/p>\n\n\n\n

The battery pack, which is continuously charged from the electricity network, has the purpose of intervening during blackout by supplying the load and ensuring service continuity.<\/p>\n\n\n\n

The input mains voltage (220V \/ 380V) initially passes through a rectifier bridge which transforms it into direct current (DC) to recharge the batteries and, subsequently, passes through an inverter which transforms and stabilizes it into alternating current to power the batteries.<\/p>\n\n\n\n

The By-pass network is used in the event of malfunctions and \/ or battery replacements.<\/p>\n\n\n\n

Fuji Electric IGBT modules for Ups<\/h3>\n\n\n\n

Fuji Electric<\/a> is a global manufacturer and supplier of IGBT modules, inverters and power semiconductors also used for UPS uninterruptible power supplies.<\/strong><\/p>\n\n\n\n

The type of IGBT modules<\/strong> most suitable for uninterruptible power supplies<\/strong> depends on the power of the individual UPS:<\/p>\n\n\n\n
