  • Patent number: 10826406
    Abstract: An alternator and a rectifier thereof are provided. The rectifier includes a rectifying transistor, a gate driving circuit and a voltage clamping circuit. The rectifying transistor generates a rectified voltage according to an input voltage and is controlled by a gate voltage. The gate driving circuit generates the gate voltage according to a difference between the rectified voltage and the input voltage.

The gate driving circuit adjusts the gate voltage in a second time interval and the difference is equal to the second reference voltage. In the second time interval, the voltage clamping circuit clamps the gate voltage by comparing the difference with the third reference voltage and the gate voltage with the fourth reference voltage.

  • Publication number: 20200220477
    Abstract: The disclosure provides an alternator and a rectifier thereof. The rectifier includes a transistor and a gate driving circuit. A control end of the transistor receives a gate voltage. The gate driving circuit generates the gate voltage according to a voltage difference between an input voltage and a rectified voltage. The gate driving circuit detects an initial time point when the voltage difference is smaller than a first preset threshold voltage, provides the gate voltage to turn on the transistor during a first time period after the initial time point, and sets the voltage difference to be equal to a first reference voltage. The gate driving circuit sets the voltage difference to be equal to a second reference voltage through adjusting the gate voltage during a second time period after the first time period.
