Inter-stage uninterruptible power supply chassis

What is an uninterruptible power supply?

Uninterruptible power supplies provide power to critical loads in the event of a power failure. Unlike emergency generators, UPS systems provide power immediately, but only for a short period of a few minutes – until a backup power supply comes online or until the load completes its shutdown sequence.

What is a three-phase uninterruptable power supply (UPS)?

Our integrated circuits and reference designs for three-phase uninterruptable power supplies (UPS) help you design reliable and robust hardware with very low input and output total harmonic distortion (THD) and increased efficiency. Modern three-phase UPS designs often require: Higher performance and reliable IGBT and MOSFET gate drivers.

Are battery-backed uninterruptable power supplies reliable?

Reliability of power sources is an increasing challenge in many sectors and battery-backed uninterruptable power supplies (UPS) are one option to protect and keep electronic equipment operating in the event of grid power failure.

What is a hybrid static/rotary UPS system?

Hybrid static/rotary UPS systems combine the main features of both static and rotary UPS systems. They have low output impedance, high reliability, excellent frequency stability, and low maintenance requirements . Typical configurations of hybrid static/rotary UPS are depicted in Fig. 18.11. They are usually used in high-power applications.
