Technology for power electronics and switching power supply is going ahead continuously in practice. The emergence of new technology will make replacement in many application products as well as open up more and more new fields. At the same time components are required to have the smaller volume and lower losses, as an important parts of electronic devices power supply is getting some improvements, for high-frequency, for high efficiency, for high reliability, for low losses, for small noise, for anti-interference, for module and so on. These are becoming a development direction for power supply, which show that these technologies will become more mature and stable, it will achieve the combinability between high-efficiency and high quality to use electric energy.
This paper focuses on industrial Din Rail Power Supply of 480W with 230V AC input and 24V DC output for research, which chosen PFC+LLC resonant half bridge converter as main topology. First introduced operating principle of the LLC resonant half bridge converter and the traditional asymmetrical half bridge converter, as well have their comparison, then introduced operating principle for PFC and design for its critical component parameters. Next step focuses on some of the characteristics and principles of LLC resonant converter and in detail analyze DC steady-state characteristics of LLC resonant converter in each frequency range, as well as design critical component parameters, also on the output synchronous rectification to be briefly introduced. Finally, made prototype for debugging and testing, as well carried out testing data, waveforms and result analysis, these results show that the design for Din Rail Power Supply are very feasible.
