To reduce loss and noise during switching of IGBTs at low cost even under changing operating conditions, the world\' s first digital gate driver IC with fully integrated automatic timing control function that achieves both single-chip integration and real-time control is developed. In order to handle various IGBTs with one type of gate driver, the proposed IC also has the world\'s first 6-bit programmable gate current function in the closed-loop active gate drivers. In the double pulse test of IGBT at 80 A, compared with the conventional single-step gate drive, the stop-and-go gate drive with automatic timing control using the proposed IC reduces the switching loss (ELOSS) by 38 % under the collector current overshoot (IOVERSHOOT)-aligned condition and reduces IOVERSHOOT by 18 % under ELOSS-aligned condition.
