Hence there is a requirement to bring this power factor close to unity. Most of the devices we use have power factor less than unity. Automatic power factor correction using microcontroller. This presentation presented by microchiptm explains how to utilize a microcontroller dspic to perform a highly integrated power factor correction.
It can be find by taking tangent of ratio of time between zero crossing of current and voltage waveforms and two successive zero crossing of voltage waveform. Here we are presenting a prototype for automatic power factor correction using pic microcontroller. This is to certify that the thesis entitled,automatic power factor correction by microcontroller 8051 submitted by sri satyasuranjeet behera,sibasis mohapatra and monalisa bisoi in partial fulfillment of. Most of the commercial and industrial installation in the. Automatic power factor controller using pic microcontroller. In recent years, the power quality of the ac system has become great concern due to the rapidly increased numbers of electronic equipment, power electronics and high voltage power system. Programming of pic micro controller for power factor correction a project reportunder the guidance ofsignature signature.
Proposed system microcontroller base automatic controlling of power factor with load monitoring is shown in fig. This involved sensing and measuring the power factor value from the load using pic and sensors. Optimal power factor correction for inductive load using pic. The technique described in this paper clearly apparent as a simple and cost effective power factor pf measurement and correction scheme by using programmable interface circuit pic microcontroller. This involves measuring the power factor value from the load using pic and proper algorithm to. This thesis describes the design and development of a power factor corrector using pic programmable interface controller microcontroller chip.
