How much is the backup voltage of the energy storage power supply

What is a backup power supply?

High-Efficiency Backup Power Supply A backup power supply is an electrical system that provides emergency power to a load when the main power source fails. An appropriate backup power supply provides instantaneous protection from main power interruptions without glitches, by supplying energy which is stored in backup capacitors or batteries.

What is a power backup & holdup system?

In a power backup or holdup system, the energy storage medium can make up a significant percentage of the total bill of materials (BOM) cost, and often occupies the most volume. The key to optimizing a solution is careful selection of components so that holdup times are met, but the system is not overdesigned.

Is a backup battery system expensive?

A backup battery system can be expensive depending on how much energy storage you need. Since battery banks are usually used in conjunction with off-grid power generation systems, the battery bank often doesn’t have to supply all of the power all of the time.

Why do you need a backup power system?

While not every backup power system offers this benefit, many provide seamless power. It immediately kicks in if your central power system fails. This means you won’t be stuck in the dark or lose access to essential appliances or systems while you set up a generator. For medical devices, this can be a matter of life and death.

What happens if a backup capacitor is charged to a higher voltage?

Charging the backup capacitor to a voltage level higher than the main power voltage results in a smaller backup capacitor value and smaller solution size to store the same amount of energy. The usable energy stored in the backup capacitor is only limited by the input voltage range of the buck-boost converter, which is 12 V for the TPS63060.

How do I choose a battery backup system?

The first step in sizing a battery backup system is to assess your household’s power needs. Consider the essential appliances and devices you want to keep running during an outage. This may include refrigerators, lighting, medical equipment, and communication devices. Make a list of these items along with their power requirements.
