Electricity is the lifeblood of homes in the corporate world. This is particularly true for companies that rely on computers and IT equipment in order to serve customers. An uninterrupted power supply system is essential to ensuring downtime is limited or nonexistent.
There are several different types of uninterrupted power supply systems to choose from. The first is known as a line interactive or off-line system in which the output is identical to the input. The UPS will only activate when there is no input voltage and power load. The second is a line interactive or online sink system. With this system, the input and output are separated by a filtering and stabilization circuit. The final option is the online double conversion system. With this system the input is rectified and reconverted into alternating current with an inverter. This allows the output voltage waveform to be completely independent from the input.
And on interrupted power supply system can address a variety of different types of power problems. Each problem has unique characteristics which the system must address.
Brown-Out
One of the most common types of power supply problems is a brownout. This is when there is a brief drop in voltage levels. Some studies estimate that this disturbance constitutes nearly 90% of the power supply problems reported by companies. The effect of this problem is a reduction of the power required by all of the devices within a facility. As a result, they are unable to operate correctly which may cause unexpected system crashes.
Power Failure
The next most common problem is a full power failure. When this happens there is no power supply at all. The effect is typically a significant loss of data and interruption of communications.
Power Spike
The third type of power supply problem is a voltage spike. This is when there is a sudden surge in voltage. They are most often caused by lightning. It typically affects electronic devices via the main power supply, serial lines, and telephone lines. It can also damage or even destroy components and devices.
Overvoltage
An overvoltage is similar to a spike however it typically only lasts a split second. Overvoltage is caused by powerful electric motors kicking on, such as large air conditioning systems. When they turn off the excess voltage is then dissipated on the electric line. Overvoltage can cause problems with computers and other devices which are sensitive to power surges as they have a low tolerance field. The result is significant stress to the components which increases wear and tear and causes premature failure.
EMI/RFI Noise
Another power problem an uninterrupted power supply system can address is access EMI and RFI noise. This noise is due to electromagnetic interference and radio interference generated by the power supply. There are a variety of factors that can cause this including lightning, load switching, generators, and industrial equipment. While it typically does not end result in a full-fledged downtime, it can cause errors and problems in computer data and telecommunication systems.
Parasitic and Harmonic Currents
Parasitic and Harmonic currents are generated by atmospheric disturbances and changes. Load variations, current generators, and electromagnetic commissions can cause this as well. These disturbances result in errors in the execution of software programs and early deterioration of computers.
Frequency Variations
The final power supply problem which can be addressed by an effective uninterrupted power supply system is frequency variations. They occur in energy produced by power supply units. These variations can cause execution errors for calculations and interpretation issues related to magnetic supporting devices such as disks and tapes.
