Here is my schematic:
Vds when Vin = 12V
Vds when Vin = 20V
Vds when Vin = 30V
My switching frequency is 50kHz, duty cycle is 0.5
When Vin = 12V, the buck converter worked properly, but when I increased the input voltage from DC power source, the Vds got distortion, so why appear this problem? and How to solve it? Thank you very much.
