摘要：

This paper deals with interleaving technique for switched-capacitor-based resonant converters (SCRCs) with a phase-shift control method. The current ripples produced by two SCRCs cancel each other in the case of the interleaving operation, and thus, the output current ripple can be significantly reduced. This paper also presents a new connection of filter capacitors making it possible to suppress the output voltage ripples, leading to a great reduction in capacitance value of the output filter capacitor. Moreover, the theoretical analysis clarifies that current sharing between two SCRCs strongly depends on the stray resistance in conventional control and that the phase-shift control can equally share the input and output currents irrespective of the stray resistance. A 2.6-kW experimental setup has confirmed that the interleaving operation can reduce the current ripples to 44% and the voltage ripples to 5% as compared with those in a conventional SCRC. © 2013 The Institute of Electrical Engineers of Japan.
