On-line UPS

-

 Definition: On-line UPS abbreviated as OUPS is a type of UPS that uses a combination of rectifier and inverter circuits in order to provide continuous power to the load from the supply source without any interruption. From continuous power here we mean that power is supplied to the load in case of availability from the source and power outage as well with zero transfer time.

On-line UPS is sometimes also known as double-conversion system. The reason for calling it so because, within an online UPS system, power conversion occurs twice as the circuit includes a rectifier and an inverter.

ill go through a detailed idea of how an online ups system works. But before that let us have an introductory idea about-

What is UPS?

UPS is an acronym used for Uninterruptible Power Supply and serves as a central element of an accurately designed power protection system. Here the name itself is indicating that it is somewhat denoting a supply source that offers continuous power i.e., without interruption.

Thus, in simplest form, one can define UPS, as a supply system that offers uninterrupted power to the ac load by converting dc into ac. Basically, there are enormous fields that require a continuous source of power without any interruption. Some of these fields are:

  • Medical care systems,
  • Safety monitoring systems,
  • IT and networking fields,
  • Data centers,
  • AMT units.

As loss of power supply in the functioning of these systems may lead to severe consequences such as removal of important data.

Alternating Current

  What Is Alternating Current? An  alternating current  can be defined as a current that changes its magnitude and polarity at regular intervals of time. It can also be defined as an electrical current that repeatedly changes or reverses its direction opposite to that of Direct Current or DC, which always flows in a single direction as shown below From the graph, we can see that the charged particles in AC tend to start moving from zero. It increases to a maximum and then decreases back to zero completing one positive cycle. The particles then reverse their direction and reach the maximum in the opposite direction after which AC again returns to the original value completing a negative cycle. The same cycle is repeated again and again. Alternating currents are also accompanied usually by alternating voltages. Besides, alternating current is also easily transformed from a higher voltage level to a lower voltage level.

SOLAR TRANSFORMERS

  The transformers required for wind power and solar DPV require special design features to meet the challenging operating conditions. The industry today has developed different types of transformers for the application. The last few decades have seen very rapid development of renewable energy, especially, distributed photovoltaic (DPV) and wind power. It is estimated that at least 40 per cent of electricity generation by year 2040 would be from renewable energy sources and this would give appreciable reduction of the present level of carbon dioxide emissions of about 10 billion tons per year. The transformer industry is rising to this challenge and has developed special transformers for the DPV generation and wind generation. Transformers are critical components in solar energy production and distribution. Historically, transformers have ‘stepped-up’ or ‘stepped-down’ energy from non-renewable sources. There are different types of solar transformers including distribution, station, su
