Difference Between UPS vs Inverter

Hello, friends, I hope you all are doing great. In today’s tutorial, we will discuss the Difference Between UPS & Inverter. Both of these UPS and inverters are used to deliver backup supplies to the electric system. The basic difference between UPS and an inverter is that when the main supply is cut off switching from the main supply occurs instantly while the inverter takes some time from pain supply to inverter. The full form of UPS is an Uninterruptable power supply. The ups consist of a battery delivering power to the load in a short time interval. The delivery of power through ups is fast and takes less time before the system is off.

The inverter is a device that is used to convert DC in the AC. Its input is ac supply and its output is dc that is used to charge the battery. In today’s post, we will have a detailed look at both UPS and inverter with a detailed compare them to find their differences. So let’s get started with a Difference Between UPS & Inverter

Difference Between UPS & Inverter

What is UPS

•  The UPS is an instrument that is used to deliver power to the output when there is no main power supply.
•  Its main function is to operate as a flywheel storage system.

•  Its switching from the main supply to the battery occurs very fastly.
•  It provides electricity as a backup.
• The main types of UPS are Offline, Online, Line interruptive or Standby UPS.
•  It has a direct link with the load.
•  This module is used in homes and industries.
• It is more expensive than the inverter.
• The main elements of its circuit are the Inverter and Controller
• Its power delivering time is less than the inverter.
•  It does not have voltage fluctuation.
• There are 3 main types of UPS.
  • • Online/Double Conversion
    • Offline Standby
    • Line-interactive
• Offline UPS protects the circuitry and is used as battery backup.
• The protective device of this module is a link to the live supply when voltage varies from a certain level it protects the system,
• Then, the load shifted from line to ups it takes twenty-five milliseconds for this process.
• the structure of line interactive ups is like the standby UPS but has an autotransformer that comes with numerous taps to change the voltage level

What is Inverter

•  The inverter is a device that is used to convert DC into ac.
•  Its main function is to transform AC power in DC power.
•  Its switching takes a longer time than the UPS.
•  It can deliver power to the load for a long time interval.

•  This module has a voltage fluctuation.
•  Its backup is electronic power.
• The commonly used types of the inverter are Stand Alone and Grid Tie Inverter.
• It is linked to the load and battery.
•  It is less costly than UPS.
•  It is only used in homes.

How does UPS work?

The UPS provides electrical power without any interruptions when there is power off or no power.

It provides power without interruptions with two features.

The first one has an energy store that is used when the electrical service is off. Normally energy storage work is done with the use of batteries and a charge controller.

It must operate instantly so that every device connected with UPS continues working when no power is connected.  Such as UPS works in data centers for the protection of hardware and data when power is off.

How does an Inverter work?

The inverter is used for conversion of DC power to AC power. it does not produce current or store it so if disconnected from DC supply AC voltage does not work.

Inverters are defined in the form of power with residential systems normally with the use of below 10KW. With that, they are made to operate in a certain range of voltage and current on the DC and AC sides.

Difference between UPS and Inverter

UPS

• The UPS is a device used for delivering power to load if the main system not working.
• The main components of UPS are rectifiers, battery inverters, and controllers.
• UPS transforms DC into AC and AC into DC at the same instant.
• There are three types of UPS offline, online, and standby
• UPS has features to charge batteries from AC supply.
• The UPS has less backup time as compared to the inverter. So it works for a short duration.
• The switching time of UPS is about 2 to 5 ms and it provides high-speed switching.
• UPS comes with AVR that offers constant output voltage with load.
• The circuit used for UPS is as complex as the inverter
• It has low-cost maintenance

Inverter

• Inverter used for power conversion into DC to AC
• its main parts are the inverter circuit and battery.
• it just converts DC into AC
• It has two types  Standalone inverter and Grid tie inverter.
• The inverter does not charge the battery itself it needs an external change controller for battery charging.
• The backup time of the inverter is higher than UPS. It provides supply based on capacity. So it has longer duration features.
• The switching time of the inverter is 200ms to 500ms. So switching of inverter is low speed than UPS.
• It does not have protection features for abnormal conditions.
• The circuit of the inverter is simple and low-cost.
