The power factor of an electronic device is measured by the ratio of power that is needs from the power supply and the power that it uses. The power factor that your devices should be at is 1.0 which means that it uses all the power that it draws. Continue reading to learn what is a power supply correction!

What is a power supply correction

  2. 2. The power factor of an electronic device is measured by the ratio of power that is needs from the power supply and the power that it uses. The power factor that your devices should be at is 1.0 which means that it uses all the power that it draws. This load produced would be linear and resistive. In retail businesses, banks, offices, schools, and virtually anywhere, including your own home, most of the devices that are used to connect us such as PC's, tablets, laptops, servers, and even office equipment like fax machines and photocopiers are powered using switched mode power supplies. When these SMPSs are not properly designed, non-linear loads can be produced. This will cause harmonic currents and even voltages to the main power source. This can cause damage to many components, overheating, and increase risk for fire, among many other risks. There are two reasons why a device might have a poor power factor. The device can either draw current that is not in phase with the main power source voltage, or the current is drawn in a non-sinusoidal waveform. Displacement is another name for when the current is out of phase.
  3. 3. This type of poor power factor is usually associated with industrial equipment while the non-sinusoidal is typically seen in person use computers and other devices that work on switched mode power supplies. A power factor correct is simply correcting the power factor to be more efficient. This is important due to the increase risk associated with having a device running on non- sinusoidal waveforms. Capacitors can be used to correct the power function. When you correct the power function, you will notice utility bills start to reduce, less system losses, the system capacity will release. The higher the power factor, the more efficient your energy consumption becomes. Any power factor below .5 is highly inefficient and costly. When you install the correct sized switch capacitors to the power distribution circuit, the result is an improved power factor which wastes a lot less energy and improved the efficiency of your business or office. Although, it may seem like a very costly project to undertake--adding capacitors, most business owners see that invest paid off in one year through saved energy expenses.
  4. 4. Keeping your power factor as close to one is also important because the utility companies in some cities can penalize you if your power factor is below .95. Utility companies in a few cities have an ability to deny you a supply of power if your power factor shows that you are pulling power that is inefficient and being wasted. When thinking about your power factor, you should also be thinking about your total system health of your computer. Making sure your computer is running efficiently can be as easy as downloading DriverAssist and running a scan on your system to search for any drivers that may need a review. This will help your device to operate more smoothly and help with the power factor correction.
