摘要： A regulator device for charging a battery from an alternator that delivers a rectified voltage including a ripple component. The device is of the type including a regulator circuit acting on the mean value of the rectified alternator voltage and includes a circuit for obtaining the main value, a threshold comparator, a time delay circuit, and a power stage for controlling the current flowing through the excitation winding of the alternator. According to the invention, the device includes a negative feedback circuit between a point downstream from the time delay circuit, and the input to the circuit for obtaining the mean value. The device also shifts the mean value downwards during periods when the excitation current is decreasing. The device is particularly applicable to increasing the frequency of regulation under a heavy load.
