Why Power Correction is required? All modern electronic devices are vulnerable to the poor power quality. What can you do about it? There are power Correction Devices are available that accept electrical power in whatever form it is available and modify the power to improve the quality or reliability required for electronic AC equipment. The power handling and performance requirements vary depending upon each application. A wide range of power correction products are available that utilizes a range of technologies and provide different degrees of protection to the connected load. 1- Isolation Transformers reduces the problem of common mode noise induced through multi current path in ground circuit or Loop. 2- Noise Filter reduce conducted electromagnetic interference (EMI) and radio-frequency interference (RFI).  Filter requires careful application if not used properly it may cause ringing effect 3-  Harmonic current Control  there are many methods available to control ...
