If there is no freewheeling diode VD in the series power adapter, when the switch tube suddenly changes from saturated conduction to cut-off, because the magnetic energy in L cannot be released, a very high voltage will be induced. This voltage is very easy to cause VT breakdown of switch tube. After connecting the freewheeling diode VD, when the switch tube changes from saturated conduction to cut-off, the magnetic energy in L is released to C2 and the load circuit through VD. On the one hand, the voltage at both ends of L is reduced, so that the voltage drop between the collector and emitter of the switch tube is equal to the input Ui value, and there is sufficient margin; On the other hand, during the VT cut-off period, L will release energy through the freewheeling diode VD, so that the load circuit can be supplemented with energy during the switch cut-off period, which will make the output voltage smoother and the efficiency of the power adapter higher.
