IGBT研究及工艺技术的日趋成熟,使得IGBT在高压大功率领域的应用十分广泛。在电子直线加速器领域,引入IGBT可以简化电路结构,提升电源系统性能。在多能量档电子辐照加速器项目中,大功率线型脉冲调制器的研制使用1.7 kV/800 A IGBT作为充电开关管,选择2SD315A-17驱动芯片作为驱动电路,工作在直接模式。除去芯片本身具有的短路和过流保护等功能外,还根据需要增加了欠压保护、故障保持和复位等功能。图1所示为IGBT IGBT research and technology matures, making the IGBT in the field of high-voltage high-power applications are very extensive. In the field of electron linear accelerator, the introduction of IGBT can simplify the circuit structure and improve the power system performance. In the multi-energy electronic radiation accelerator project, the development of high-power linear pulse modulator using 1.7 kV / 800 A IGBT as a charge switch, select 2SD315A-17 driver chip as the driver circuit, work in direct mode. Remove the chip itself has short-circuit and over-current protection and other functions, but also increased under-voltage protection, fault hold and reset functions. Figure 1 shows the IGBT
