What is the difference between a UPS and an inverter

Difference between a UPS and an inverter

Inveeter

However, people are still confused by the difference between a UPS and an inverter because the UPS and the inverters are backup power sources during the main power interruption.

We rely heavily on electronic equipment that works with electricity such as fans, lighting, air conditioning, appliances, computer etc. Whenever there is a power cut, the supplies of electricity to this equipment is cut off and stop working, however, if we have a backup such as UPS and inverter we can ensure the power supply to the equipment and not bother about power cuts.

The inverters are preferred more for general electrical appliances whose work is not affected by prolonged delays between the switching of power supplies (Red-Inverter), while the UPS is used for electronic devices such as computers, servers, workstations, medical equipment that perform critical tasks and cannot tolerate delays in switching between power supplies (Red-UPS).

An off-line UPS (the standard) switches to the batteries in 3 to 8 milliseconds after the main power has been lost, while the inverter changes in approximately 500 milliseconds much slower than the UPS.

UPS:

UPS means uninterruptible power supply, this means that the time of switching between the network and the battery of the UPS is very fast almost imperceptible, therefore the important and critical equipment such as computers, medical instrumentation etc is not turn off, with which we will not lose data.

A UPS is a complete system that consists of many parts that include among others the batteries, a charge controller, and transfer circuits to switch between the network and backup battery, and an inverter. An inverter is needed because the battery can only store DC power and we need to convert it back to AC (alternating current) to match the AC voltage of the appliances connected to the main power line.

The UPS is nothing more than an inverter with a built-in battery charger. Commonly the UPS can give support between 5 to 120 minutes depending on how loaded it may be. The main intention of the UPS is to provide the reservation only for a small time while you keep the programs, the data, finish some surgical procedure or wait for the entrance of a power plant or group.

Inverter:

The inverters are simple converters between the battery, DC, AC and source. An inverter inverts the direct current to an alternating current; under normal conditions, the power supply feeds the load directly. During a power outage, the inverter receives the battery supply and converts it from DC to AC power and provides power to the electrical equipment. The purpose of the inverters is to provide backup power for appliances, lights, fans, and equipment that are not critical.

The inverter uses a flat plate or a tubular battery to store electricity, therefore requires continuous maintenance, which means filling the cells with distilled water at regular intervals of time. The inverter does not protect against line anomalies as if the UPS does.

Description                                           UPS Inverter:

 

UPS means uninterrupted power supply. The inverter is a device that converts electricity from DC to AC,

 

Function It is an electrical circuit (device) that instantly supports the power supply of an electronic device. The equipment continues to run smoothly and there is no damage to them. An inverter consists of a circuitry that converts AC to DC and stores it in the battery. When the power supply is turned off, that direct current is converted back to AC and transmitted to the respective electronic device.

 

Beginning

 

First, convert AC to DC power to charge the battery which then converts DC power to AC (inverter) and this AC power is supplied to the load. However, the UPS monitors the input voltage level and processes it in terms of voltage regulation.

UPS = battery charger + inverter

 

 

The inverter converts the DC power (stored in its battery) into the AC power supplied to the devices. Normally, AC power charges the battery. It uses relays and sensors to detect when to use direct current or AC power, for DC power.

 

Backup time Backup power for a short duration Backup power for a long duration

 

Types (A) UPS offline, (b) UPS online and (c) UPS interactive line. (A) Square wave, (b) Quasi-wave, (C) Sine wave

 

Main part Rectifier / charger, inverter, regulator Inverter and controller.

 

Transference time before a cut 3 to 8 milliseconds. 500 milliseconds

 

Voltage fluctuations

 

While voltage fluctuations in the input power can be adjusted by the UPS, it is desired that the output voltages are as smooth as possible. In the smoothing of the voltage outputs, the UPS is considered better compared to the inverter.

 

The inverter does not protect against voltage fluctuations.

 

Circuit technology The UPS circuit is much more sophisticated than the inverter Circuit the inverter has a simpler circuit than the UPS

 

UPS Price More expensive than an inverter. The inverter is less expensive than UPS

 

Usage The UPS is used for electronic applications such as computers, servers, network switches, workstations, medical equipment, processing equipment that perform critical tasks and cannot tolerate power supply delays. The inverters are preferred more for general electrical applications as their work is not affected by the prolonged delays in the switching of the power supply.

 

Protection The UPS provides protection against voltage spikes, voltage drops, main frequency instability, and harmonic distortions. The inverter does not provide protection against line anomalies.

 

Battery Maintenance-free sealed battery (SMF) Flat plate or tubular battery requires maintenance

 

Maintenance of the battery Does not require any maintenance. Requires continuous maintenance, you need to fill the cells with distilled water at regular intervals of time

 

More power Consumption due to constant battery Charge less

 

 

Conclusion:

The UPS and the inverter provide backup supply to the electrical system. Two major differences between the UPS and the inverter are:

The switching from UPS to the main source and the battery is very immediate so it is used to provide backup power for important or critical electronic equipment, while in the inverter the switching of the power from the network to the battery takes time for what is used to provide a load to less important equipment.
