“…5. The feed forward control is about the calculation of the duty cycle values responsible for the system's unity power factor [25], [26]. For input voltage V in(t), output voltage Vout(t), d(n) as duty cycle for n th switching cycle, t(n) and t(n+1) as the beginning instant of n th and (n+1) th switching cycle and Ts as the switching period, the equations for the ON and OFF state of conventional boost converters are given by equation ( 4) and ( 5) respectively;…”

A Pulse Width Modulation method is presented in this paper for the harmonics and circulating current reduction in the power converters system. The power converter considered for this research work is a boost converter connected in an interleaved topology in a single setup. The Common-Mode Circulating Current CMCC are studied in detail in this interleaved topology setup. For the Differential-Mode Circulating Current DMCC, these two identical interleaved setups are then connected in parallel. A PWM control method is suggested for harmonic elimination and control of circulating currents inside the circuit. This method results are compared with Feed Forward and AICMC control methods. Simulation results are presented to show the effectiveness of this proposed model.

“…The control technology mentioned above is not flexible enough, the dynamic response speed is not fast enough when the load changes, and the load range is not wide enough. In order to solve the above shortcomings, predictive current control has been proposed [8] . Predictive current control has a better preference on the current reference track, increasing system bandwidth and fasting transient response.…”

The traditional PFC control adopts the PI algorithm of the double-loop structure, but the PI parameter designed at this time is aimed at the inductor current continuous mode (CCM). When the PFC enters a heavy or light load, the converter inevitably enters the inductor current discontinuous mode (DCM). If the control parameters of CCM are still used at this time, the system may become unstable and reduce load response speed. Therefore, an optimized predictive current control is proposed, which calculates the duty cycle in CCM and DCM separately in advance, and then adopts the corresponding optimal duty cycle according to the detected inductor current conduction mode. With this algorithm, the PFC can operate in mixed conduction mode. It has a wider load range and faster load response speed than PI. Finally, through PLECS, the algorithm is verified by simulation.
