“…While there are numerous control algorithms for boost-type PFC circuits, the most traditional one is the PID control algorithm. However, the model predictive control algorithm has become among the highly significant and widely embraced advanced technology [4] [5]. Applying a model predictive control algorithm at reference [6] utilized it for a permanent magnet syschronous motor.…”

Power factor correction circuits are being used more extensively, and with that, the requirements and standards have become increasingly stringent. To improve the power factor of the circuit, thereby improving its operational efficiency and mitigating the load effects in boost power factor correction circuits, reducing Total Harmonics Distortion is crucial for improving the quality of the current. An improvement upon the conventional dual-loop PID control algorithm has been proposed. It involves integrating Model Predictive Control into the current loop design and incorporates a Luenberger observer. Model Predictive Control methods can be applied for the control of multivariable systems, especially in complex multivariable systems, as they exhibit strong robustness. Finally, by performing both simulation and experimental validations and analyzing the data results, it is shown that under full load conditions, the power factor λ is 0.968, the efficiency η is 91.11%, the voltage total harmonic distortion Uthd is 1.88%, and the current total harmonic distortion Ithd is 7.04%. These data results strongly confirm the performance of the control mechanism proposed in this paper.

“…④ From the angle of shielding, adopt shell shielding technology and device shielding technology. The LLC resonant converter in reference [3], [11] only use shielding technology to solve the EMI common-mode noise problem, and without use primary side winding and secondary side winding staggered technology to suppress dv/dt noise sources. In reference [13], EMI common-mode noise of buck converter is analyzed, but electromagnetic field modeling analysis and common-mode noise conduction path are not studied.…”

In this paper, CM noise suppresion and magnetic elements winding loss optimization design of a cascade power module based on GaN design are carried out (the front stage is buck converter, the second stage is LLC resonant converter). To suppress CM noise, the front buck converter adopts planar stagger reverse coupling inductance, by establishing reverse stagger coupling buck converter CM noise model and conduction path model, the equivalent capacitance can effectively reduced, thus further reducing CM noise current. A staggered winding structure is proposed for second stage LLC resonant converter, compared and calculated LLC resonant transformer winding electromagnetic field characteristics with different structure. a novel shielding and cancellation technique is proposed for LLC resonant converter, by establishing LLC converter CM noise shielding model and the equivalent capacitance can effectively reduced, thus further reducing CM noise current. In order to improve the LLC resonant converter efficiency, winding copper foil optimal thickness is proposed. Experimental results show that power module with winding optimization and shielding technology can effectively suppress the CM noise and improve efficiency, CM noise can reduced 12-20dB, the peak efficiency improved about 1% after copper foil thickness is optimized.INDEX TERMS Common-mode, reverse stagger winding structure, shielding technology, buck converter, LLC resonance converter.
