【摘要】：逆导型IGBT(RC-IGBT)是将IGBT功能与续流二极管功能集成在一个芯片上,实现了在相同封装体积下,可获得更大的功率密度,由于IGBT与二极管紧密的移相热耦合,在相同散热条件下,RC-IGBT允许的工作结温更高。同时,RC-IGBT的本征二极管还受到栅极电压控制,通过栅极电压控制策略,可以降低器件损耗,优化系统特性。介绍了RC-IGBT的基本工作原理和二极管退饱和控制特性,研究了RC-IGBT应用于变流器系统的损耗优化控制策略,分析了应用RC-IGBT的单相脉宽调制(PWM)整流器的工作特性与损耗特性。通过一个具体的应用工况运行仿真,分析对比了RC-IGBT和普通IGBT在PWM整流器应用中的损耗特性。结果显示,应用RC-IGBT后总体损耗有所降低,验证了RC-IGBT退饱和脉冲控制的有效性。
[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.
