Abstract

The invention discloses a resonant converter system and a control method of the same. The resonant converter system comprises a resonant converter for receiving an input voltage and outputting an output voltage, and a composite control device which is coupled with the resonant converter, is used to produce a drive signal and adjusts a phase angle and a frequency of the resonant converter when theresonant converter works in an abnormal state, so as to achieve lower voltage gain and less loss in a relatively easier way.

Description

technical field [0001] The present invention relates to a resonant converter system, in particular to a resonant converter system with a hybrid control apparatus. Background technique [0002] The development trend of DC / DC converters, like most power products, is towards high efficiency, high power density, high reliability and low cost. . Because the resonant converter usually adopts the pulse frequency modulation (Pulse Frequency Modulation, PFM) control method, it is relatively easy to realize the zero voltage switching of its switch, and it is easy to meet the high efficiency and high power density requirements of the converter, so it has been widely used. [0003] Although the resonant converter has the advantages of high conversion efficiency under normal working conditions, when it is working in abnormal conditions, such as when the line is started or the output current is limited, for the frequency converter that only uses frequency change There are still some pro...
