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.
