An electronic actuator device and a control method thereof are provided. The electronic actuator device includes a plurality of first and second power switches and a driving circuit. The first power switches respectively provide a first reference voltage to a plurality of voltage receiving ends of a motor respectively according to a plurality of first control signals. The second power switches respectively provide a second reference voltage to the voltage receiving ends respectively according to a plurality of second control signals. The driving circuit generates the first and second control signals. In a braking operation, the first power switches are turned on during a plurality of first time periods, and the second switches are turned on during a plurality of second time periods that are alternate and non-overlapped with the first time periods. An interval time period is present between each adjacent two of the first and second time periods.

Electric actuator device and control method thereof

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.
