Patent attributes
A synchronous rectifier alternator and a power allocation method thereof are provided. The synchronous rectifier alternator includes an alternator, a synchronous rectifier circuit and a controller. The alternator converts mechanical energy to alternating current (AC) electrical energy. The synchronous rectifier circuit converts the AC electrical energy to direct current (DC) electrical energy and provides the DC electrical energy to a load. The controller detects a voltage level of the DC electrical energy. When the controller detects that the voltage level is higher than or equal to a first threshold voltage value, the controller controls ONs and OFFs of first transistors and second transistors of the synchronous rectifier circuit, such that at least one of regulator diodes of the synchronous rectifier circuit, a stator of the alternator and the load consume power of the alternator.
