Hello,
I am developing a 2 phase interleaved buck converter.
Input Voltage : ~ 120VDC
Output Voltage : 1V to 50VDC
Output Current : 100A Max for any voltage(1to50V)
I attached my circuit diagram.
My problems starts when output current rises about 50A.
For below 50A everthings looks perfect. After 50Amps one of the channels mosfet got burned.
Note : I tested my circuit with 50ohms gate resistor. Because of the high switching ripples.
