About
Offline, also known as standby, UPS is mainly used for small offices and home offices, also called SOHO, due to their low cost. They are power protection devices that provide backup power during electrical outages but also offer basic power protection features such as surge protection and voltage regulation. Offline UPS systems usually operate between 0 kVA and 10 kVA. They mainly use discrete power semiconductor solutions and are usually divided into low-frequency and high-frequency transformer-based systems. In these systems, the AC line voltage is present, and a relay bypasses the inverter, which remains off. The battery charger operates to maintain full charge, but if the AC power fails then relay switches the UPS output over to the inverter, which starts up after a short interruption of 10-20 ms to supply backup power. Due to this short interruption, offline UPS are only viable in systems where this is acceptable, such as home offices or small offices.?
While they may not offer advanced power conditioning features, offline UPS units provide essential backup power to protect valuable electronics from power disruptions and voltage fluctuations.
Infineon's portfolio of semiconductor solutions for low frequency offline UPS transformers is designed for use with 50-60 Hz switching, iron core transformers that use external lead-acid car batteries at 12 V or 12 V + 12 V in series.
Our solutions utilize sine or square wave output voltage and are designed for a full-bridge bidirectional inverter/charger with parallel MOSFETs in the 30-60 V range. Infineon products are also robust against AC line surges and enable the trend from leaded to SMD components.?
If you select Infineon products for your application in this space, you will unlock benefits such as low ?RDS(on), high current capability, as well as devices constructed with rugged silicon, and that are available in scalable footprints. Check out the block diagram on this page to learn more about our offerings and tailor it to your exact specifications.
Uninterruptable power supply (UPS) for use in small office or home office (SOHO) environments typically include MOSFET-based inverters that operate from 12 V or 24 V lead-acid batteries (24 V systems are comprised of two series-connected 12 V batteries). Higher battery voltages are required to limit operating currents in higher power-rated systems. 42 V and 72 V systems also exist for the same reason, but these are somewhat less common. Batteries may be external or internal to the UPS; car batteries are used externally and sealed lead-acid batteries internally.
Infineon MOSFETs enable this and more with their quality, durability, and impressive performance.
