摘要：AbstractIn this paper, a hybrid control method of pulse width modulation (PWM) and pulse frequency modulation (PFM) is proposed, which can greatly enhance the control performance of the CLLLC resonant converter to output voltage, reduce the ripple of the output voltage and improve the efficiency of the converter. This paper analyzes the theory of hybrid control and introduces the operating principle of the hybrid control method. In addition, the hybrid control method ensures that the power MOSFETs devices realize zero voltage switching (ZVS) and improve the efficiency of converter. Finally, the performance of the proposed hybrid control method is compared with the traditional PFM control and verified by simulation.
