The flyback switching power supply is mostly used in the low and medium power range, such as 2w~100w. Basic principle of flyback power supply When the power supply is in a steady state, at the time ton, the MOS transistor Q1 is turned on, and the inductor current of the prima

Type of output diodeSecondary winding output diode D1 usually chooses a Schottky diode or an ultra-fast recovery diode, one is because the reverse recovery time trr of these two diodes is short, and the other is because the forward voltage Vf drop of these two diodes is small.If the diode reverse re
