Power Factor Correction Using Parallel Boost Converter

Abstract

Power factor, the ratio between the active or average power and the apparent power forms a very essential parameter of the power system. It is indicative of how effectively the active power of the system has been utilized. With rapid development in power semiconductor devices, the usage of power electronic systems has expanded to a new and wide application range that include residential, commercial, aerospace and many others. Power electronic interfaces e.g. switch mode power supplies (SMPS) have ended up being better over conventional direct power supplies. Be that as it may, their non-straight conduct puts a question mark on their high effectiveness. The current drawn by the SMPSs from the line is of low quality and contorted bringing about a high total harmonic distortion (THD) and low power factor (PF). Individually, a gadget with consonant current does not posture much significant issue however when it is utilized on a gigantic scale the utility power supply condition will get decayed. Other unfavorable consequences for the force framework incorporate expanded sizes of impartial streams in three-stage frameworks, overheating in transformers and instigation engines and so forth. Henceforth, there is a consistent requirement for force component change and diminishment of line current sounds; improvement of new circuit topologies and control methodologies for power factor correction.
