Abstract:
The various embodiments and example provided herein are generally directed to novel multiphase resonant converters. In an embodiment, a multiphase resonant converter comprises N unit resonant converters having inputs and outputs connected in parallel, respectively. Each unit converter comprises an inverter, a LLC series resonant tank, and a rectifier. In a preferred embodiment, the inverters of the N unit converters are driven by N drive signals phase-shifted 2π/N degrees apart. During operation, the current of the multiphase converter is shared among the unit converters, resulting in a smaller current in each unit converter. The smaller current in each unit converter reduces conduction losses, thereby increasing the efficiency of the multiphase converter. In addition, the smaller current in each unit converter reduces the amount of stress placed on individual components of the converter allowing for the use of lower tolerance components. Further, the multiphase converter has automatic current sharing ability.
