摘要： A resonant power converter circuit stage can be configured to: i) receive a rectified voltage derived from an AC input voltage; ii) convert the rectified voltage to an internal voltage based on the application of a duty cycle that varies depending on the input voltage and the output dynamic load, and iii) convert the internal voltage to a DC output voltage for driving the dynamic load based on application of a switching frequency that varies depending on a dynamic load. The efficiency of the power converter system can be increased by setting the internal DC voltage magnitude to be load adaptive. Variation of the internal DC voltage depending on the dynamic load enables the resonant converter circuit to operate at a switching frequency near its optimum resonance frequency. This method results in constant power converter system efficiency over a wide range of loading. In order to further increase the light load efficiency interleaved resonant power converters with load, adaptive internal DC voltage are used.
