Modeling of quantum parallel resonant converters-a new parallel resonant converters controlled by integral cycle mode

Quantum parallel resonant converters (QPRCs), a dual converter of quantum series resonant converters (QSRCs), and a subset of parallel resonant converters (PRCs) operating on zero-voltage switching conditions are modeled. It is shown that the QPRC can be operated as a Cuk converter with an equivalent capacitor, or as a buck or buck-boost converter with an additional equivalent capacitor. The approach to modeling these converters is verified by analysis and simulation results for the PRC. DC and AC characteristics of the quantum PRCs can be obtained from these models. Therefore, the QPRC can be designed to be similar to the QSRC, i.e. to be controlled with closed-loop feedback and to have advantages such as low device switching stress, reliable high-frequency operation, low electromagnetic interference, etc.<
