Abstract

An alternator and a rectifier thereof are provided. The rectifier includes a transistor and a gate voltage control circuit. The transistor is controlled by a gate voltage. The gate voltage control circuit generates the gate voltage according to a voltage difference between an input voltage and a rectified voltage. During a first time interval after the voltage difference drops to a first preset threshold voltage, the gate voltage control circuit determines whether the voltage difference is less than a second preset threshold voltage, and decides whether to provide the gate voltage to turn on the transistor. When the transistor is turned on, the voltage difference substantially equals to a first reference voltage. And during a second time interval, the gate voltage control circuit regulates the gate voltage to set the voltage difference substantially to a second reference voltage.
