What is a UPS and how does it work?
A UPS (Uninterruptible Power Supply) system ensures that your devices continue to operate in the event of a power disruption or outage. It does this by providing power from the energy stored in the batteries in the battery cabinet. The UPS system can be equipped with lithium-ion batteries, offering up to 34.6 kWh of energy and can support up to 5 MW of power.
What is a power device in a UPS system?
In addition, the power device of the UPS system contains the static transfer switch (STS), the rectifier (AC/DC), the inverter (DC/AC), and the bypass device, and it is used to accomplish power conversion among the power input, the MS-FESS and the loads.
Can MS-fess be used as energy storage device in UPS system?
The experimental results of the speed regulation. The MS-FESS could be used as the energy storage device in the UPS system to realize the charging and discharging, such that the high-efficiency conversion between the kinetic energy and the electric energy could be accomplished.
What is a magnetically suspended flywheel energy storage system (MS-fess)?
The magnetically suspended flywheel energy storage system (MS-FESS) is an energy storage equipment that accomplishes the bidirectional transfer between electric energy and kinetic energy, and it is widely used as the power conversion unit in the uninterrupted power supply (UPS) system.
What is an uninterruptible power supply (UPS)?
An Uninterruptible Power Supply (UPS) ensures continuity of the power supply regardless of fluctuations or interruptions in the utility supply. This is an essential requirement for critical applications such as IT/data centers, stock exchanges, medical scanners, radar systems etc.
What is the battery capacity of the UPS system?
The UPS system uses batteries in the battery cabinet to provide power during disruptions. The battery capacity is 34.6 kWh. The system is lithium-ion based and can support up to 5 MW in parallel.
