Advanced IGBT chip technology for industrial motor drive applications

The latest 6th generation (6G) IGBTs chip technology suitable for industrial motor drive applications is described in this paper. The 6G-IGBTs with micro-P structure provide better turn-on di/dt controllability, lower turn-off oscillation and better Von-Eoff trade-off relationship. By using the 6G-IGBTs with micro-P, the turn-on power dissipation can be reduced compared to the conventional IGBTs with floating p-base under the operating condition to set the same FWD reverse recovery dv/dt. The trade-off relationship between the on-state voltage drop and the turn-off power dissipation has been improved without the turn-off oscillation even in a severe condition. The impact of the micro-P structure on these characteristics has been demonstrated by using 600V and 1200V class IGBTs.
