The pulse width prediction control technique hasbeen widely used in AC-DC converters with power factor correctionin boost topology, where satisfactory results have beenreported without the need to use classic control laws. However,this technique has not been explored for other types of ACDCconverters with power factor correction. In this work, theuse of this technique is proposed in an AC-DC converter withpower factor correction in a half-bridge boost topology. Thistopology presents high efficiency because it uses the least numberof semiconductors compared to other topologıes. In this techniquethe duty cycle is predicted by processing the average values ofstate and input variables of the converter in half bridge boosttopology, using only four multiplications and five additions, whichimplies less complexity in its implementation. For its validationsimulations were performed using MATLAB R simulink, whereit was possible to observe values of power factor and THDcomparable with other control methods such as non-linear carriercontrol, and conventional analog control, both reported in theliterature.
