Engineer explains: Switching power supply design—transformer process
This series of articles starts from the theoretical basis. Experienced former engineers explain the design of switching power supplies and explain the difficulties. This series contains almost all common topological circuits and is designed for self-study engineers. Personally crafted, I hope it can help everyone get out of confusion and get on the right track as soon as possible.
Calculate primary inductance
The K value is the current continuous ratio mentioned above. Ip2 defined in the calculation book above is the rising edge of the current and Ip1 is the trailing edge of the rising current. Therefore, when K=0, the transformer works below the critical mode. To prevent calculation errors, it is generally customary to take 0.001.
Intermittent mode Ip is ΔI;
Obtained ΔI from--》E*T=L*ΔI:
Lp=(Vinmin*Tonmax)/ΔI
At this time, the inductance required by the transformer primary is obtained.
