Modeling and Application of PFC Chip L4981A
Abstract: In order to improve the efficiency of power supply design using PSIM simulation software in power supply design process, combining with the working principle and characteristics of L4981A, a L4981A simulation model is established which is the lack of PSIM Library. An APFC circuit in ST AN827 application note is used to simulate and verify the model of L4981A. Compared with its application note, it is found that the static characteristics of modeling match well with the application note. Results show that the model can describe the operating characteristic of actual circuit. The model has a very good reference value in analysis and design of power equipment. The idea provides an effective analysis and implementation method for other control chips.
