Abstract


Power electronics and switching power supply technology applications demand constant development , the emergence of new technologies will, in turn, many applications product replacement , but also to open up more applications updated . Electronic components smaller, lower energy consumption . Switching power supply as an integral part of electronic equipment are constantly improved , high-frequency , high efficiency , high reliability , low power consumption , low noise , anti-jamming and modularization has become the development direction of the switching power supply , this also indicates that these technologies will continue to become more and more mature and stable , and combined with each other to achieve high - efficiency electricity and high - quality electricity . In this paper, a 480W, 230V AC input , 24V DC output AC / DC -rail power supply for the study, main circuit topology selection PFC LLC resonant circuit . First introduced the LLC resonant half-bridge converter and traditional asymmetrical half-bridge converter works and contrast ; design the PFC main circuit works and the main component parameters ; then focuses on the characteristics and principles of the LLC resonant converter , the detailed analysis of the DC steady-state characteristics of the LLC resonant converter in the respective frequency ranges , and for the main components of the power part of the parameters of design and calculation ; synchronous rectification of the output portion are briefly analysis introduction . Final design to produce power prototype debugging and testing , test data , waveforms and results . Through the analysis of the test results , verify the feasibility of the design .
