The use of electronic ballast and switching mode power supply in energy conservation has caused power quality problems and less reliable output voltage. Power factor correction (PFC) converters and output voltage are conventionally regulated using the PID controller to condense the current harmonics, increase the power factor and regulate the system output voltage. In general, their output is not very appropriate for non-linear systems. Because this approach is highly non-linear, the PID controller gain optimized in this paper using the grey wolf optimization algorithm to increase the power factor and boost the stability of the AC to DC process output voltage. The simulation studies to demonstrate the efficacy of the proposed grey wolf optimized PID controller is performed in MATLAB Simulink to achieving balanced performance and high power factor.
