Abstract:This paper presents a phase shift plus PWM control strategy for the novel resonant bridge modular multilevel switched-capacitor converter.The proposed method ensures that almost all switching devices keep zero current switching or zero voltage switching,which achieves a high system efficiency.Meanwhile,the output voltage is regulated and the loop peak current is limited in a proper range.The impacts of the switching phase of metal-oxide-semiconductor field-effect transistors (MOSFETs) on both the output voltage and the loop peak current are deduced,respectively.By means of simulation software Saber and hardware platform,the proposed characteristics of soft switching,output voltage,and peak current are verified well.
