Zusammenfassung:	A device, system and method protects from overvoltages. A power control device includes a component (310) configured to be powered according to a duty cycle. The power control device includes a controller (330) configured to determine the duty cycle that places the component on or off. The power control device includes a comparator (335) configured to determine when the duty cycle is off and an overvoltage is being experienced by the component. When the duty cycle is off and the overvoltage is being experienced by the component, the comparator selects a circuit pathway (345, 350) including a clamping device (350). 一种设备、系统和方法防止过压。一种功率控制设备包括被配置为根据占空比而被通电的部件(310)。功率控制设备包括控制器(330)，控制器(330)被配置为确定使部件导通或关断的占空比。功率控制设备包括比较器(335)，比较器(335)被配置为确定占空比何时为关断以及部件是否正在经历过压。当占空比为关断且部件正在经历过压时，比较器选择包括钳位设备(350)的电路路径(345，350)。
