The circuit diagram is as follows:

The switching power supply chip viper22a DS pole voltage waveform is as follows:

Do you have any good ways to eliminate the spikes at the moment when the mos tube is turned on? Thank you!

You can parallel RC absorption on the secondary rectifier tube to see the effect. In addition, according to the ringing, the design of the transformer seems to be problematic. Adjust the primary turns and inductance to see.

There are many ways to eliminate DS spikes, reduce the turns ratio, strengthen the absorption of the secondary diode, and use a slow tube for the primary RCD absorption loop diode.
