Research on the Design of Quasi Resonant Flyback Switching Power Supply Based on Electronic Information

Abstract With the popularization and in-depth development of electrification and electronization, the demand for switching power supply in all walks of life is also constantly strengthened, especially for the key indicators and parameters of switching power supply, such as performance, efficiency and reliability. Based on this, this paper first analyses the connotation and components of flyback switching power supply, then studies the design of quasi resonant flyback power supply, and finally gives the realization path and strategy of quasi resonant flyback switching power supply.
