| Abstract: | A new high speed gate-drive circuit applicable to soft-switching full bridge PWM converters is proposed.The circuit shows excellent features such as transformer isolation,no ringing of the gate-source voltage of the switches,programmable dead time,insensitivity to component value variation,negative gate-source voltage at switch-off,operating frequency up to 100 kHz.The operation,analysis and design considerations are illustrated and verified on a 3 kW,100 kHz IGBT based experimental circuit. |
