| Abstract: | A novel IGBT gate method which is easily implemented within the IGBT gate driver for the PWM voltage source inverters is presented. Using this method,the gate drivers of the upper and the lower IGBT's within a inverter phase leg can receive the ideal (without dead-time) PWM signals,and will not cause the direct link shoot through problem. The principle of the proposed IGBT gate is describled,and the simulation results verifying the proposed method are presented. |
