Online controller optimization for a voltage-doubler boost rectifier with high power factor

The design of converters is essential for the proper use of electrical energy. Half-bridge topology represents a suitable conversion scheme to implement a boost rectifier converter. Consequently, this article proposes the parameter optimization of a proportional-integral-derivative (with filter) controller for a half-bridge boost rectifier with a high power factor. Regarding the high simulation time for the converter, stochastic hill-climbing and simulated annealing algorithms are employed for the optimization process. The results display that the optimized controller allows suitable values for the power factor and output waveform. The controller parameters obtained through optimization algorithms result in a high power factor of 0.9934 when the half-bridge boost rectifier is operating at full load.
