[Abstract]:Inverse IGBT (RC-IGBT) integrates the IGBT function with the reflow diode function on a single chip, and achieves greater power density under the same package volume, because of the tight phase-shifting thermal coupling between IGBT and diode. Under the same heat dissipation condition, the working junction temperature allowed by RC-IGBT is higher. At the same time, the intrinsic diode of RC-IGBT is also controlled by gate voltage. Through the gate voltage control strategy, the device loss can be reduced and the system characteristics can be optimized. This paper introduces the basic principle of RC-IGBT and the characteristics of diode desaturation control, and studies the optimal loss control strategy of RC-IGBT applied to converter system. The performance and loss characteristics of (PWM) rectifier with single phase pulse width modulation (RC-IGBT) are analyzed. The loss characteristics of RC-IGBT and IGBT in the application of PWM rectifier are analyzed and compared through a specific application condition operation simulation. The results show that the overall loss is reduced after RC-IGBT, which verifies the effectiveness of RC-IGBT desaturation pulse control.
