“…Several authors have analyzed the operation of the CPFC topologies, from the most classic such as: boost [9] [10], buck-boost [11], flyback [12] [13] and half bridge boost [14] [15], up to the most recent: no diode bridge [2] [16] [17], interleaved [18] and flyback with dual-purpose inverter [19]. Within these, the AC-DC converters with power factor correction in half bridge boost topology (CPFC-HBB) has the simplest conversion circuit and with fewer switches [20], so the main advantage of the CPFC-HBB is that it presents high efficiency, since at any time there is only a voltage drop, which is produced by the working semiconductor [21]. Another advantage of the CPFC-HBB is to allow its power flow to be bidirectional; this explains why the CPFCHBB is widely used in power factor correction applications [22].…”

The pulse width prediction control technique has been widely used in AC-DC converters with power factor correction in boost topology, where satisfactory results have been reported without the need to use classic control laws. However, this technique has not been explored for other types of ACDC converters with power factor correction. In this work, the use of this technique is proposed in an AC-DC converter with power factor correction in a half-bridge boost topology. This topology presents high efficiency because it uses the least number of semiconductors compared to other topologies. In this technique the duty cycle is predicted by processing the average values of state and input variables of the converter in half bridge boost topology, using only four multiplications and five additions, which implies less complexity in its implementation. For its validation simulations were performed using MATLAB R Simulink, where it was possible to observe values of power factor and THD comparable with other control methods such as non-linear carrier control, and conventional analog control, both reported in the literature.
