slugPOWER QUALITY IMPROVEMENT USING PWM VOLTAGE REGULATOR
Journal Title: International Journal of Management, IT and Engineering - Year 2011, Vol 2, Issue 5
Abstract
In this present paper, stress has been laid upon the present scenario of power quality in every grid. With more and more use of non linear electrical loads instead of linear loads, we get increased efficiency with reduced power requirements; however this degrades the power quality of whole power system. Power quality is basically determined by the voltage magnitude and frequency in a system. To improve it, we can use voltage regulators, filters, etc. In this paper use of voltage regulator using PIC16F877A microcontroller has been presented, which works on concept of PWM voltage regulator and can be called as a smart circuit. It provides good automated regulation without consuming much power. Only major drawback is the presence of harmonics in the output, thus improvement in the circuit is required from this point of view.
