Reduction In Total - Harmonic- Distortion for AC To DC Converter With Improved Power Factor Using Boost Converter With PID Controller

Electrical Engineering

The present scenario is trending towards quality power supply. There are different parameters which decides the power quality like continuity, wave shape, wave distortion, ripples, flickering, harmonics etc. In this paper the method of reduction of total harmonic distortion for AC – to- DC converter with improved power factor by implementing a boost converter along with the PID controller. To prolong the life time of electronic circuits the electrolytic capacitor is excluded as the electrolytic capacitors weakens with time. The power-factor-correction (PFC) circuit for ac-to-dc converters is based on boost conversion with power decoupling. The controlled conventional machine is hired to reallocate the excessive electricity to the inefficient side of the ac side through decoupling the input power into a dc aspect . Instead of using a large electrolytic capacitor with the boost converter , the conventional energy law follows the track of minimum errors in Vref and Pref which is configured by PI controller gate pulse input to power switches. A MATLAB/SIMULINK circuit is designed with an ac voltage source of 90 V , 110 V and 130 V at 60 Hz. In the design case, a surprisingly small inductor is needed. In addition, small losses are delivered by means of the additional power switches. These benefits are increased by using high switching speed power switches. Simulation results on a SIMULINK circuit version have established the effectiveness of the proposed technique
