IC693PBM200 在中电机驱动器中，处理器通常在超低电压 （SELV） 电源域中运行，以优化性能。与提供给普通音频设备或PC端口的电源类似，这些电压和电流水平足够低，因此不会被视为危险。不需要防止意外与人接触的预防措施。通过这种方式，无需隔离即可轻松访问处理器人机界面。然而，IGBT和电机相位通常在几百伏或更高的电压下工作，无论是相对于彼此还是相对于SELV功率域。因此，IGBT栅极、驱动器输出以及为其供电的偏置电压都是危险的。IGBT栅极电压域和供电的SELV电源域之间需要隔离，并且需要域本身之间的功能隔离。偏置电源变压器需要一个隔离式输出绕组，每个隔离电源域至少需要两个连接引脚。
IC693PBM200 除了电压幅度外，考虑电机相位的共模压摆率（电压变化率或dV/dt）。图2是演示板IGBT驱动电机相位切换的观察结果。该测量显示压摆率为11 V/ns。偏置电压取决于此共模电压压摆，并且不得受到其干扰。
