| 摘要 | A device for supplying electric power includes a rectifier, an adaptive voltage clamping circuit, and a DC-DC voltage regulator. The rectifier receives electrical power, and is electrically connected to an input line of the adaptive voltage clamping circuit. The adaptive voltage clamping circuit includes a power transistor, a voltage feedback circuit, and a controller. The DC-DC voltage regulator is electrically connected to the adaptive voltage clamping circuit and, in one embodiment an actuator. The controller monitors the voltage feedback circuit and controls the power transistor to a fully open state to transfer electric power to the DC-DC voltage regulator when the voltage level supplied to the DC-DC voltage regulator is less than a threshold. The controller controls the power transistor in a linear state to regulate the voltage transferred to the DC-DC voltage regulator when the voltage level supplied to the DC-DC voltage regulator is greater than the threshold. | ||||||
