The wire between the converter and IGBT driver must as short as possible. External filter capacitors should be connected as close as possible to the converter and the IGBT driver. To ensure the high peak gate current, the filter capacitors should be low impedance. The output average power of the IGBT driver should be less than the output power of DC-DC module. In order to avoid over temperature damage for long time short-circuit, the recommended short-circuit time is less than ten minutes at 25°C.
