Generalized quantum resonant converters using a new concepts of quantum resonant switch

Abstract

For generalization of the soft-switching-based quantum resonant converters including AC/AC conversion applications, a new concept of quantum resonant switches which include quantum series resonant switches (QSRS) and quantum parallel resonant switches (QPRS) is proposed. The quantum resonant switches are modeled as an equivalent inductor for QSRS and equivalent capacitor for QPRS. The basic conventional PWM (pulse-width-modulated) DC/DC and AC/AC converters can be changed to the corresponding quantum resonant converters with the same global characteristics by replacing the link inductor or capacitor with the proposed QSRS or QPRS. Thus, the conventional modeling and design methods can also be applied to quantum resonant converters. In this procedure, a number of useful quantum resonant AC/AC converter which can improve the characteristics of the high-frequency DC-link AC/AC converters are proposed. Experimental verifications of the modeling of the quantum resonant switches and the topologies and basic operations of the proposed quantum resonant DC/DC and AC/AC converters are presented.<>
