Due to the relationship between the gate-emitter connection inductance LG, RG, and Cies, if oscillation occurs in the gate drive loop, component damage may occur due to malfunction and unsaturated operation. The minimum value of RG without oscillation increases in proportion to √LG. Therefore, the inductance should be reduced as much as possible while keeping RG above the recommended value.
