A small scale prototype of the proposed PFC converter with dual control is designed with input of 220 Vac, 50 Hz and measurements of improved parameters are verified with the theoretical analysis. The Dual DFO + PI controller achieved constant average power factor of 0.97 p.u. The single stage AC–DC converter with dual control is simulated in MATLAB and compared with conventional controller and topologies to prove its superiority. This dual control achieved constant power factor, efficiency and reduced harmonics even with the input voltage variations, load changes with wider control range. DFO is used in inner loop to control the input current to maintain unity power factor and reduce harmonics. In dual loop, PI is used in outer loop for voltage DC regulation and efficiency improvement. Dual control is proposed to maintain the power factor at unity irrespective of input voltage variations and load changes of the PFC converter. The topology of the selected PFC converter is the integration of SEPIC and LLC circuit. A dispersive flies optimization (DFO) and PI based dual control is proposed to improve the power factor and efficiency of the converter. In this paper, a single stage DC/DC PFC converter is studied. Simultaneously maintaining unity power factor and delivering high efficiency is considered to be the key requirement. A standard PFC (LED drives) converter has to adapt with the input voltage variations and provide required load voltage and load current. Power factor correction (PFC) converters are used in many applications and are quickly replacing conventional light source due to its high efficiency and longevity.
